upper compartment with a perforated bottom upon which to place the
coffee. To make one cup of this infusion, place half an ounce of
ground coffee in the upper compartment and six fluid ounces of
water into the bottom. Put the biggin over a gas lamp. After three
minutes the water will boil. When steam appears, take the biggin
from the fire and pour the water into a cup and thence immediately
into the top of the biggin where it will extract the berry by
replacement. (Here follows an experiment.)
This experiment shows that loss of weight is no criterion that
coffee is properly roasted, neither is the color (by itself) nor
the temperature, nor the time.
Next we experimented to ascertain whether the aroma developed by
roasting coffee and which is lost might not be collected and added
to the coffee at pleasure. An attempt was made to drive the
volatile oils from roasted coffee by steam and make a dried extract
of the residual coffee to which the oils were to be later added.
Two attempts were made and both failed. It appears that but a small
quantity of the aroma is lost in roasting and that is mixed with
bad smelling vapors from which it is impossible to free it.
Then we tried to make a potable coffee by making an aqueous extract
of raw coffee, evaporating to dryness and roasting the residue.
(Here follows the experiment.)
This also was unsuccessful. The great trouble here is a dark shiny
residue, which, while tasteless, is very disagreeable to look at.
In the preparation of coffee by boiling, two and a half times as
much matter is extracted as by biggin.
The proper method of roasting coffee is as follows: It should be
placed in a cylinder and turned constantly over a bright fire. When
white smoke begins to appear, the contents should be closely
watched. Keep testing the grains. As soon as a grain breaks easily
at a slight blow, at which time the color will be a light chestnut
brown, the coffee is done. Cool it by lifting some up and dropping
it back with a tin cup. If it be left to cool in a heap there is
great danger of over-roasting. Keep the coffee only in air-tight
vessels. _Measure_ the infusions, a half ounce of coffee to six
ounces of water per cup.
All "extracts of coffee" are worthless. Most of them are composed
of burned sugar, chicory, carrots, etc.
In 1883, an authority of that day, Francis B. Thurber, in his book,
_Coffee; from Plantation to Cup_, which he dedicated to the railroad
restaurant man at Poughkeepsie, because he served an "ideal cup of
coffee", came out strongly for the good old boiling method with eggs,
shells included. This was the Thurber recipe:
Grind moderately fine a large cup or small bowl of coffee; break
into it one egg with shell; mix well, adding enough cold water to
thoroughly wet the grounds; upon this pour one pint of boiling
water: let it boil slowly for ten to fifteen minutes, according to
the variety of coffee used and the fineness to which it is ground.
Let it stand three minutes to settle, then pour through a fine
wire-sieve into a warm coffee pot; this will make enough for four
persons. At table, first put the sugar into the cup, then fill
half-full of boiling milk, add your coffee, and you have a
delicious beverage that will be a revelation to many poor mortals
who have an indistinct remembrance of, and an intense longing for,
an ideal cup of coffee. If cream can be procured so much the
better, and in that case boiling water can be added either in the
pot or cup to make up for the space occupied by the milk as above;
or condensed milk will be found a good substitute for cream.
In 1886, however, Jabez Burns, who knew something about the practical
making of the beverage as well as the roasting and grinding operations,
said:
Have boiling water handy. Take a clean dry pot and put in the
ground coffee. Place on fire to warm pot and coffee. Pour on
sufficient boiling water, not more than two-thirds full. As soon as
the water boils add a little cold water and remove from fire. To
extract the greatest virtue of coffee grind it fine and pour
scalding water over it.
John Cotton Dana, of the Newark Public Library, says he remembers how in
his old home in Woodstock, Vt., they had always, in the attic, a big
stone jar of green coffee. This was sacred to the great feast days,
Thanksgiving, Christmas, etc. Just before those anniversaries, the jar
was brought forward and the proper amount of coffee was taken out and
roasted in a flat sheet-iron pan on the top of the stove, being stirred
constantly and watched with great care. "As my memory seems to say that
this was not constantly done," says Mr. Dana, "it would seem that, even
then, my father, who kept the general store in the village, bought
roasted coffee in Boston or New York."
At the close of the century, there were still many advocates of boiling
coffee; but although the coffee trade was not quite ready to declare its
absolute independence in this direction, there were many leaders who
boldly proclaimed their freedom from the old prejudice. Arthur Gray, in
his _Over the Black Coffee_, as late as 1902, quoted "the largest coffee
importing house in the United States" as advocating the use of eggs and
egg-shells and boiling the mixture for ten minutes.
_Latest Developments in Better Coffee Making_
Better coffee making by co-operative trade effort got its initial
stimulus at the 1912 convention of the National Coffee Roasters
Association. As a result of discussions at that meeting and thereafter,
a Better Coffee Making Committee was created for investigation and
research.
The coffee trade's declaration of independence in the matter of boiled
coffee was made at the 1913 convention of the National Coffee Roasters
Association, when, after hearing the report of the Better Coffee Making
Committee, presented by Edward Aborn of New York, it adopted a
resolution saying that the recommendations met with its approval and
ordering that they be printed and circulated.
The work done by the committee included "the first chemical analysis of
brewed coffee on record", a study of grindings, and a comparison of the
results of four brewing methods. Its conclusions and recommendations
were embodied in a booklet published by the National Coffee Roasters
Association, entitled _From Tree to Cup with Coffee_, and were as
follows:
ROASTING
The Roaster or "Coffee Chef" is the only cook necessary to a good
cup of coffee. He sends it to the consumer a completely cooked
product.
In the roasting process the berries swell up by the liberation of
gases within their substance. The aromatic oils contained in the
cells are sufficiently developed or "cooked", and made ready for
instantaneous solution with boiling water, when the cells are
thoroughly opened by grinding.
The roasting principles of different green coffees vary. Trained
study and a nice science in timing the roast and manipulating the
fire is necessary to a perfect development of aroma and flavor.
The drinking quality is largely dependent upon the experienced
knowledge of the coffee roaster and his scientific methods and
modern machinery, by which the coffee is not only roasted, but
cleaned, milled and completely manufactured to a high point of
perfection.
In their National Association work, the wholesale roasters are
giving the public new facts and valuable information, from
scientific researches, investigations, etc.
GRINDING. The roasted berry is constructed of fibrous tissues
formed into tiny cells visible only under the microscope, which are
the "packages" wherein are stored the whole value of coffee, the
aromatic oils. Like cutting open an orange, the grinding of coffee
is the opening of surrounding tissue and pulp, and the finer it is
cut the more easily are the "juices" released.
The fibrous tissue itself is waste material, yielding, by boiling
or too long percolations, a coffee colored liquid which is fibrous
and twangy in taste, has no aromatic character, and contains
undesirable elements.
The true strength and flavor of roasted coffee is ground out, not
boiled out. The finer coffee is ground, the more thoroughly are the
cells opened, the surfaces multiplied, and the aromatic oils made
ready for separation from their husks. Hence it follows that:
Coarse ground coffee is unopened coffee--coffee thrown away.
The finer the grind, the better and greater the yield. With
pulverized coffee (fine as corn meal) the fully released aromatic
oils are instantaneously soluble with boiling water.
In ground coffee the oils are standing in "open packages," escaping
into the air and absorbing moisture, etc., necessitating quick use
or confinement in air proof and moisture proof protection.
BREWING. From scientific researches by the National Coffee
Roasters' Association, including the first chemical analysis on
record of brewed coffee, produced by various brewing methods, the
fundamental principles of coffee making have been clearly
established. These principles are simple, and when once understood
equip any person to intelligently judge the merits and defects of
the various coffee making devices on the market. They constitute
the law of coffee brewing, and may be stated as follows:
Correct brewing is not "cooking." It is a process of extraction of
the already cooked aromatic oils from the surrounding fibrous
tissue, which has no drinkable value. Boiling or stewing cooks in
the fibre, which should be wholly discarded as dregs, and damages
the flavor and purity of the liquid. Boiling coffee and water
together is ruin and waste.
The aromatic oils, constituting the whole true flavor, are
extracted instantly by boiling water when the cells are thoroughly
opened by fine grinding. The undesirable elements, being less
quickly soluble, are left in the grounds in a quick contact of
water and coffee. The coarser the grind the less accessible are the
oils to the water, thus the inability to get out the strength from
coffee not finely enough ground.
Too long contact of water and coffee causes twang and bitterness,
and the finer the grind the less the contact should be. The
infusion, when brewed, is injured by being boiled or overheated. It
is also damaged by being chilled, which breaks the fusion of oils
and water. It should be served immediately, or kept hot, as in a
double boiler.
Tests show that water under the boiling point, 212°, is
inefficient for coffee brewing, and does not extract the aromatic
oils[378]. Used under this temperature, it is a sure cause of weak
and insipid flavor. The effort to make up this deficiency by longer
contact of coffee and water, or repeated pouring through, results
in no extraction of the oils, but draws out undesirable elements,
such as coffee-tannin, which is soluble in water at any temperature
and is governed by the time of contact.
Coffee-tannin, which is not the commercial tannic acid, is
eliminated to practically nothing in the quick brewing methods.
The chemical analysis of brewed coffee shows the following:
Coffee Tannin Comparative
per Cup Proportions
Percolator method,[379] fine gran. 2.90 grains --------
5 minutes' steeping
Boiling Method, medium " 2.35 " ------
Steeping Method, " " 2.31 " -----
Filtration (or Drip) Method } 0.29 " -
Pulverized }
Brewing is the final manufacturing process of coffee. All previous
perfection is dependent upon it. Like food products which lose
nutritive value by bad cooking, coffee loses its best values by
wrong brewing. Brewed by the very simple correct methods, it is an
unfailingly clear, fragrant, taste-charming beverage, universally
loved and scientifically approved.
The committee made a further report in 1914, and some of the findings
were subsequently published in an association booklet called _The Coffee
Book_, used in connection with the second National Coffee Week campaign
in 1915. In it were these:
GRINDING DEFINITIONS
_Powdered_ _Pulverized_
Like--flour. Like--not coarser than
fine corn meal.
_Very Fine and Fine_ _Medium_
Like--from corn meal to Like--coarse granulated
fine granulated sugar. sugar.
Also, the committee emphasized its previous findings, particularly this
one: "Filter bags should be kept in cold water when not in use. Drying
causes decomposition. Keeps sweet if kept wet. Use muslin for filter bag
and pulverized granulation."
The association brought out this same year, on recommendation of the
committee, its Home coffee mill, an "ideal and standard coffee mill for
home use." It was a wall mill equipped with a glass-front metal hopper
and employing a ratchet spring-lock nut and double-action grinders. The
mill was later improved with an all-glass hopper and a tumbler bracket.
More than 20,000 of these mills have been sold.
At the suggestion of the author, the efficiency of nine different
coffee-making devices (including boiling and drip pots, pumping
percolators, cloth and paper filters) was investigated in the
laboratories of the Mellon Institute of Industrial Research of the
University of Pittsburgh in 1915; and Dr. Raymond F. Bacon submitted a
report that showed that the boiling method produced the highest
percentage of caffetannic acid and caffein; the French drip process the
lowest. The investigation disclosed also a more palatable brew at 195°
to 200° F. than at the boiling point.
Another notable contribution to the science of coffee brewing was made
by the Home Economics Laboratories of the University of Kansas in 1916.
The experiments extended over one year. They showed that strength and
color in coffee brews are independent of blend and price and are most
fully obtained by pulverized granulation, which was found to be the most
efficient; that the consumer pays for flavor and that filtration yielded
the best brew. The French drip, or true percolator, did not figure in
these experiments.
At the 1915 convention of the National Coffee Roasters Association, Mr.
Aborn reported that 4,000 copies of the committee's findings on grinding
and brewing had been given away: and the facts were further circulated
in 2,000,000 booklets issued during two years. He told of tests which
showed that while there might be reasons of commercial expediency for
packing ground coffee, it could not be defended as a quality principle;
also that plate-grinders produced a more efficient drawing granulation
than roller grinders, and that the idea that the steel-cut process
eliminates dirt was an absurdity, as "the finest ground coffee is not
dirt but coffee in its most efficient drawing condition." He added, "I
have paid no attention to chaff removal in these tests as the
uselessness of such removal has been repeatedly shown up." The reference
here was to his 1914 and 1913 reports, in which it was stated that
"removing the chaff in the steel-cut process does not remove any of the
tannin, and for this purpose the steel-cut process is wholely futile,
and a wasteful and unnecessary tax upon cost", and that "the removal of
the chaff appreciably affects the flavor and depreciates the cup value."
This report repeated previous findings against the pumping percolator as
producing an inefficient brew and being a very faulty utensil. Mr.
Aborn concluded his report by saying:
The old time boiling method has fewer and fewer defenders and holds
its own only as a superstition. I therefore pass it over as a
discarded issue.... It is but repetition of former reports for me
to say that pulverized granulation is the most efficient
granulation; that it assures the highest quality of brew and the
lowest proportion of coffee to a given strength; that it is the
most saving and most satisfying grinding for all to use; that it
(the coffee) must be fresh ground; that the filtration method is
the most correct in fundamental principles and that used with a
muslin bag it assures the consumer coffee of the purest, finest
flavored quality, highest health value and sure economy.
The campaign of education was continued during 1916, producing
encouraging results among schools, colleges, the medical fraternity,
newspapers, with the trade and the consumer. It marked the first big
constructive work combining the practical and scientific phases of
grinding and brewing methods. In his report at the 1916 convention of
the National Coffee Roasters Association, Mr. Aborn reviewed the four
years work, and pointed out what had been accomplished. He told of a new
booklet, to be called the _True Book on Coffee Grinding and Brewing_,
and an educational exhibit box for schools about to be issued. Due to
opposition which developed from trade interests that were putting out
steel-cut and other grinds of coffee not favored by the committee, and
also because many members thought the association should not exploit any
particular method of grinding or brewing, it was decided to make no
further publication of the coffee grinding and brewing conclusions of
the committee until they had been confirmed by laboratory research.
Boiling and filtration tests in the mountains of the Yellowstone Park by
W.H. Aborn in 1916 showed that the limit of coffee brewing was reached
at an altitude of nine thousand feet.
At the 1916 meeting, Dr. Floyd W. Robison of the Detroit Testing
Laboratories, read a notable paper entitled "What do we know about
coffee?," which hailed coffee as a food product, warned the roasters to
beware of half-facts, and urged the importance of a research laboratory.
It was published and given distribution by the association.
The educational exhibit box showing samples of coffee from plantation to
cup, including five different grinds, was issued in 1917, and sold for
one dollar.
The Better Coffee Making Committee also published in this year a booklet
entitled _Coffee Grinding and Brewing_ in which it summarized its work
to date, and presented its special plea for cotton-cloth filters as the
ideal coffee-making device.
This booklet aroused considerable discussion, particularly between those
who favored the paper filter and those who, with Mr. Aborn, believed
cotton cloth, such as muslin, to be the most efficient strainer.
"Cotton", argued Mr. Aborn, "is an ideal sanitary strainer because it
contains no chemical or questionable manufacturing element."
It was pointed out by Dr. Floyd W. Robison that while cotton cloth, such
as muslin, does give a fairly clear coffee, it is not so clear as by the
methods where a filter paper is used. He said:
Both methods have serious objectionable features. The muslin bag,
particularly, is decidedly unsanitary, especially when used in
restaurants and hotels. It is rarely kept clean, and one who has
frequented restaurants and many hotel kitchens knows that it lends
itself to very unclean and unsightly methods of handling. The food
inspector has to check this up perhaps as often as any one feature
about a restaurant.
The objection to the filter paper is not at all on the ground of
sanitation. It is ideal in this respect. The claim is made, and at
least, in part, substantiated, that it does hold back valuable
features of the brew.
There are many points about the filter that have not been
considered at all. Mr. Calkin believes that the very best type of
filter is a bed of coffee itself, and I must say this has the
sanction of good laboratory experience.
I.D. Richheimer[380], attacking the cotton cloth filter, said:
It is a known fact that the fats in coffee are very dense and
represent twelve to fifteen percent of the coffee weight. These
fats--due to the simplest chemical action of contact with air,
moisture and continued heat--begin a fermentation in the completed
beverage. In the cloth-filtering process--due to the rapid passage
of water through grounds almost as quickly as poured--the largest
percentage of fats is carried into the beverage. Fat being lighter
than water rises to the top of water if given a certain amount of
time during the brewing process. Were there no fats (which ferment)
in coffee there would be no need for placing cloth-filtering
material under water, as suggested, to keep them from becoming
sour.
In the booklet referred to, Mr. Aborn expressed himself as follows on
the filtration method:
The filtration method is not new, but well tried, thoroughly proven
and long used, though often incorrectly. It is the method followed,
more or less correctly, by all of the first-class hotels in the
world. It is controlled by no patent or proprietary device, and
requires a most inexpensive equipment. For a perfect result it but
demands an accurate adherence to simple but vital principles.
Deviations from these fundamentals, though apparently slight, cause
failure. When they, and the necessary _exact_ following of them,
are clearly understood, any person, even a small child, can brew
coffee with unvarying success.
The first point to consider in filtration is the dimensions of the
filter bag, or container of the ground coffee, in relation to the
quantity of coffee used and the granulation of same. If the filter
be a muslin bag, free on all sides, the filtering surface is
considerable and permits the necessary quick passage of water
through the grounds, provided the bag is of a wide enough diameter
as to prevent too great a depth of grounds through which the water
cannot quickly penetrate. The error of too narrow a filter is a
common one. It causes a delayed filtration, which means undesirably
long contact of water and coffee and also the cooling of the liquid
which in a correct, undelayed filtration is smoking hot at
completion. The bag should also not be too long or be allowed to
hang or soak in the liquid. A filter bag set tightly into a pot
against its sides, thus surrounded with impenetrable walls, is
greatly reduced in filtering surface, and the filtration is thereby
slackened.
The filter material should not be too coarse in texture, like
cheese cloth, or too heavy and impenetrable, like very heavy
muslin. A moderate weight muslin, not too light, is efficient.
The degree of granulation also, of course, affects the rate of
flow. The coarser the grind the faster the flow, which permits a
larger quantity of coffee to a given diameter of filter bag.
A most frequent fault in the use of the filtration method is the
failure to understand the fine degree of grinding necessary to the
best results. When the grind is not sufficiently fine the
extraction is, of course, weak. A fine grind (like fine cornmeal)
is essential. It does not retard the flow if the filter is of right
dimensions. A powdered grind (like flour) is so fine that it is apt
to "mat" itself into a resisting floor.
Many users of the filtration method pour the liquid through more
than once. This gains some added color, but adds undesirable
element, depreciates flavor and is especially inadvisable when the
grind is sufficiently fine. _One pouring_ only is recommended for
the best results.
The chinaware, or glazed earthenware pot, sometimes called the
French drip pot, with a chinaware or earthenware sieve container
for the grounds at the top through which the water is poured, being
free of all metal, is inviting in purity and in hygienic merit.
Together with the filter bag, it is subject to the above remarks on
dimensions. A chinaware sieve cannot be made as fine as a metal
sieve and cannot of course hold very fine granulation as can cotton
cloth. More coffee for a given strength is, therefore, required.
The upper container should be wide enough, for a given quantity of
coffee, as to allow an unretarded flow, and the more openings the
strainer contains the better.
In any drip, filtration or percolating method the stirring of the
grounds causes an over-contact of water and coffee and results in
an overdrawn liquor of injured flavor. If the water does not pass
through the grounds readily, the fault is as above indicated and
cannot be corrected by stirring or agitation. Many complaints of
bitter taste are traced to this error in the use of the filtration
method.
It is not necessary to pour on the water in driblets. The water may
be poured slowly, but the grounds should be kept well covered. The
weight of the water helps the flow downward through the grounds.
Care should be taken to keep up the temperature of the water. Set
the kettle back on the stove when not pouring. If the water is
measured, use a small heated vessel, which fill and empty quickly
without allowing the water to cool.
In 1917, _The Tea and Coffee Trade Journal_ made a comparative
coffee-brewing test with a regulation coffee pot for boiling, a pumping
percolator, a double glass filtration device, a cloth-filter device, and
a paper filter device. The cup tests were made by E.M. Frankel, Ph.D.;
and William B. Harris, coffee expert, United States Department of
Agriculture. The brews were judged for color, flavor (palatability,
smoothness), body (richness), and aroma. The test showed that the paper
filtration device produced the most superior brew. The cloth-filter,
glass-filter, percolator, and boiling pot followed in the order named.
At the 1917 convention of the National Coffee Roasters Association, John
E. King, of Detroit, announced that laboratory research which he had had
conducted for him showed that the finer the grind, the greater the loss
of aroma, and so he had selected a grind containing ninety percent of
very fine coffee and ten percent of a coarser nature, which seemed to
retain the aroma. He subsequently secured a United States patent for
this grind. Mr. King announced also at this meeting that his
investigations showed there was more than a strong likelihood that the
much-discussed caffetannic acid did not exist in coffee--that it most
probably was a mixture of chlorogenic and and coffalic acids.
The World War operated to interfere with the coffee roasters' plans for
a research bureau; and in the meantime the Brazil planters, in 1919,
started their million-dollar advertising campaign in the United States,
co-operating with a joint committee representing the green and roasted
coffee interests. In the following year (June, 1920), this committee
arranged with the Massachusetts Institute of Technology to start
scientific research work on coffee, the literature of the roasters'
Better Coffee Making Committee being turned over to it; and the
Institute began to "test the results of the committee's work by purely
analytical methods."
The first report on the research work at the Massachusetts Institute of
Technology was made by Professor S.C. Prescott to the Joint Coffee Trade
Publicity Committee in April, 1921. The committee gave out a statement
saying that Prof. Prescott's report stated that "caffein, the most
characteristic principle of coffee, is, in the moderate quantities
consumed by the average coffee drinker, a safe stimulant without harmful
after-effects."
There was no publication of experimental results; but the announced
findings were, in the main, a confirmation of the results of previous
workers, particularly of Hollingworth, with whose statement, that
"caffein, when taken with food in moderate amount is not in the least
deleterious," the report was quoted as being in entire agreement.
At the annual convention of the National Coffee Roasters Association,
November 2, 1921, Professor Prescott made a further report, in which he
stated that investigations on coffee brewing had disclosed that coffee
made with water between 185° and 200° was to be preferred to coffee made
with the water at actual boiling temperature (212°), that the chemical
action was far less vigorous, and that the resulting infusion retained
all the fine flavors and was freer from certain bitter or astringent
flavors than that made at the higher temperature. Professor Prescott
announced also that the best materials for coffee-making utensils were
glass (including agate-ware, vitrified ware, porcelain, etc.), aluminum,
nickel or silver plate, copper, and tin plate, in the order named[381].
The Joint Coffee Trade Publicity Committee's booklet on _Coffee and
Coffee Making_, issued in 1921, was very guarded in its observations on
grinding and brewing. It avoided all controversial points, but it did go
so far as to say on the general subject of brewing:
Chemists have analyzed the coffee bean and told us that the only
part of it which should go into our coffee cups for drinking is an
aromatic oil. This aromatic element is extracted most efficiently
only by fresh boiling water. The practice of soaking the grounds in
cold water, therefore, is to be condemned. It is a mistake also to
let the water and the grounds boil together after the real coffee
flavor is once extracted. This extraction takes place very quickly,
especially when the coffee is ground fine. The coarser the
granulation the longer it is necessary to let the grounds remain in
contact with the boiling water. Remember that flavor, the only
flavor worth having, is extracted by the _short_ contact of boiling
water and coffee grounds and that after this flavor is extracted,
the coffee grounds become valueless dregs.
The report contained also the following helpful generalities on coffee
service and the various methods of brewing in more or less common use in
the United States in 1921:
Although the above rules are absolutely fundamental to good Coffee
Making, their importance is so little appreciated that in some
households the lifeless grounds from the breakfast Coffee are left
in the pot and resteeped for the next meal, with the addition of a
small quantity of fresh coffee. Used coffee grounds are of no more
value in coffee making than ashes are in kindling a fire.
After the coffee is brewed the true coffee flavor, now extracted
from the bean, should be guarded carefully. When the brewed liquid
is left on the fire or overheated this flavor is cooked away and
the whole character of the beverage is changed. It is just as fatal
to let the brew grow cold. If possible, coffee should be served as
soon as it is made. If service is delayed, it should be kept hot
but not overheated. For this purpose careful cooks prefer a double
boiler over a slow flre. The cups should be warmed beforehand, and
the same is true of a serving pot, if one is used. Brewed coffee,
once injured by cooling, cannot be restored by reheating.
Unsatisfactory results in coffee brewing frequently can be traced
to a lack of care in keeping utensils clean. The fact that the
coffee pot is used only for coffee making is no excuse for setting
it away with a hasty rinse. Coffee making utensils should be
cleansed after each using with scrupulous care. If a percolator is
used pay special attention to the small tube through which the hot
water rises to spray over the grounds. This should be scrubbed with
the wire-handled brush that comes for the purpose.
In cleansing drip or filter bags use cool water. Hot water "cooks
in" the coffee stains. After the bag is rinsed keep it submerged in
cool water until time to use it again. Never let it dry. This
treatment protects the cloth from the germs in the air which cause
souring. New filter bags should be washed before using to remove
the starch or sizing.
DRIP (OR FILTER) COFFEE. The principle behind this method is the
quick contact of water at full boiling point with coffee ground as
fine as it is practical to use it. The filtering medium may be of
cloth or paper, or perforated chinaware or metal. The fineness of
the grind should be regulated by the nature of the filtering
medium, the grains being large enough not to slip through the
perforations.
The amount of ground coffee to use may vary from a heaping
teaspoonful to a rounded tablespoonful for each cup of coffee
desired, depending upon the granulation, the kind of apparatus used
and individual taste. A general rule is the finer the grind the
smaller the amount of dry coffee required.
The most satisfactory grind for a cloth drip bag has the
consistency of powdered sugar and shows a slight grit when rubbed
between thumb and finger. Unbleached muslin makes the best bag for
this granulation. For dripping coffee reduced to a powder, as fine
as flour or confectioner's sugar, use a bag of canton flannel with
the fuzzy side in. Powdered coffee, however, requires careful
manipulation and cannot be recommended for everyday household use.
Put the ground coffee in the bag or sieve. Bring fresh water to a
full boil and pour it through the coffee at a steady, gradual rate
of flow. If a cloth drip bag is used, with a very finely ground
coffee, one pouring should be enough. No special pot or device is
necessary. The liquid coffee may be dripped into any handy vessel
or directly into the cups. Dripping into the coffee cups, however,
is not to be recommended unless the dripper is moved from cup to
cup so that no one cup will get more than its share of the first
flow, which is the strongest and best.
The brew is complete when it drips from the grounds, and further
cooking or "heating up" injures the quality. Therefore, since it is
not necessary to put the brew over the fire, it is possible to make
use of the hygienic advantages of a glassware, porcelain or
earthenware serving pot.
BOILED (OR STEEPED) COFFEE. For boiling (or steeping) use a medium
grind. The recipe is a rounded tablespoonful for each cup of coffee
desired or--as some cooks prefer to remember it--a tablespoonful
for each cup and "one for the pot." Put the dry coffee in the pot
and pour over it fresh water _briskly boiling_. Steep for five
minutes or longer, according to taste, over a low fire. Settle with
a dash of cold water or strain through muslin or cheesecloth and
serve at once.
PERCOLATED COFFEE. Use a rounded tablespoonful of medium fine
ground coffee to each cupful of water. The water may be poured into
the percolator cold or at the boiling point. In the latter case,
percolation begins at once. Let the water percolate over the
grounds for five or ten minutes depending upon the intensity of the
heat and the flavor desired.
In response to a request by the author, Charles W. Trigg has contributed
the following discussion of coffee making:
VARIOUS ASPECTS OF SCIENTIFIC COFFEE BREWING
Before converting it into the beverage form, coffee must be
carefully selected and blended, and skillfully roasted, in order
thus far to assure obtaining a maximum efficiency of results. No
matter how accurately all this be done, improper brewing of the
roasted bean will nullify the previous efforts and spoil the drink;
for roasted coffee is a delicate material, very susceptible to
deterioration and of doubtful worth as the source of a beverage
unless properly handled.
There probably never was produced a drink which so fits into the
exacting desires of the human appetite as does coffee. Properly
prepared, it is a delightful beverage: but incorrectly made, it
becomes an imposition upon the palates of mankind. Sensitive though
coffee is to improper manipulation, the best procedure for brewing
it is also the easiest. Cheap coffee well made excels good coffee
poorly made.
CONSTITUENT CONCEPTS. The roasting of green coffee causes an
alteration in the constitution of its constituents, with the result
that some of the compounds present therein which were originally
water-soluble are rendered insoluble, and some which were insoluble
are converted into soluble ones. A portion of the original caffein
content is lost by sublimation. The aromatic conglomerate, caffeol,
is formed, and a considerable quantity of gas is produced, a
portion of which, developing pressure in the cells of the beans,
pops, or swells, them so as to increase the size of each individual
bean. The constituents which are water-soluble after the
torrefaction may be generally classified as heavy extractives and
light aromatic materials. The percentages and nature of these
materials in the roasted coffee will vary with the type of coffee
and with the roast which it is given. In general, and in particular
for purposes of comparison of methods of brewing, they may be
considered to be the same and to occur in about the same
proportions in all coffees.
The heavy extractives are caffein, mineral matter, proteins,
caramel and sugars, "caffetannic acid", and various organic
materials of uncertain composition. Some fat will also be found in
the average coffee brew, being present not by virtue of being water
soluble, but because it has been melted from the bean by the hot
water and carried along with the solution.
The caffein furnishes the stimulation for which coffee is generally
consumed. It has only a slightly bitter taste, and because of the
relatively small percentage in which it is present in a cup of
coffee, does not contribute to the cup value. The mineral matter,
together with certain decomposition and hydrolysis products of
crude fiber and chlorogenic acid, contribute toward the astringency
or bitterness of the cup. The proteins are present in such small
quantity that their only rôle is to raise somewhat the almost
negligible food value of a coffee infusion. The body, or what might
be called the licorice-like character of coffee, is due to the
presence of bodies of a glucosidic nature and to caramel.
As has been previously pointed out[382], the term "caffetannic
acid" is a misnomer; for the substances which are called by this
name are in all probability mainly coffalic and chlorogenic acids.
Neither is a true tannin, and they evince but few of the
characteristic reactions of tannic acid. Some neutral coffees will
show as high a "caffetannic acid" content as other acid-charactered
ones. Careful work by Warnier[383] showed the actual acidities of
some East Indian coffees to vary from 0.013 to 0.033 percent. These
figures may be taken as reliable examples of the true acid content
of coffee, and though they seem very low, it is not at all
incomprehensible that the acids which they indicate produce the
acidity in a cup of coffee. They probably are mainly volatile
organic acids together with other acidic-natured products of
roasting.
[Illustration: SECTION OF ROASTED BEAN MAGNIFIED 1,000 TIMES]
We know that very small quantities of acid are readily detected in
fruit juices and beer, and that variation in their percentages is
quickly noticed, while the neutralization of this small amount of
acidity leaves an insipid drink. Hence it seems quite likely that
this small acid content gives to the coffee brew its essential
acidity. A few minor experiments on neutralization have proven the
production of a very insipid beverage by thus treating a coffee
infusion. So that the acidity of certain coffees most apparently
should be attributed to such compounds, rather than to the misnamed
"caffetannic acid."
The light aromatic materials, and the other substances which are
steam-distillable, i.e. which are driven off when coffee is
concentrated by boiling, are the main determining factors in the
individuality of coffees. These compounds, which are collectively
called "caffeol", vary greatly in the percentages present in
different coffees, and thus are largely responsible for our ability
to distinguish coffees in the cup. It is these compounds which
supply the pleasingly aromatic and appetizing odor to coffee.
All of these compounds, with the possible exception of the
proteins, are easily soluble in both hot and cold water. The fact
that a clear coffee extract made with hot water does not show any
precipitate immediately upon cooling, proves that cold water will
give as complete an extraction as hot water. However, speed of
extraction is materially increased with rise in temperature, due to
the fact that the rate and degree of solubility of the substances
in water, and the diffusion of the water through the cell walls of
the coffee, are accelerated. Also, the resistance which the fat
content of the bean offers to the wetting of the coffee, and the
persistency of the "enfleurage" action of the fat in retaining the
caffeol, are less with hot than with cold water. Accordingly, the
speed of extraction is increased by using hot water, and the
efficiency of extraction procured per unit time of subjection to
water is higher.
Prolonged contact of coffee with water results in the hydrolysis of
some of the insoluble materials and subsequent extraction of the
substances thus formed. The rate of hydrolysis also increases with
temperature: and as these compounds are of an astringent or bitter
nature, the solution obtained upon boiling coffee is naturally
possessed of a flavor unpleasant to the palate of the connoisseur.
Boiling of the coffee infusion after it has been removed from the
grounds also has a deleterious effect, as the local overheating of
the solution at the point of application of the heat results in a
decomposition, particularly if the solution be converted into steam
at this point, leaving a thin film of solids temporarily exposed to
the destructive action of the heat. Some of the more delicate
constituents are unfavorably affected by such treatment, and
undergo hydrolysis and oxidation. The products thus formed are
thrown into relief in the flavor by the loss of the aromatic
properties through steam distillation which is incidental to
boiling.
It is a well known fact that re-warming a coffee brew has a
unfavorable effect upon it. This is probably due in part to a
precipitation of some of the water-soluble proteins upon standing,
and their subsequent decomposition when heat is applied directly to
them in reheating the solution. The absorption of air by the
solution upon cooling, with attendant oxidation, which is
accentuated by the application of heat in re-warming, must also be
considered, as well as the other effects of boiling as set forth,
and the action of the materials of which the coffee pot is
constructed upon the solution.
PHYSICAL CONCEPTION. The coffee bean is composed of a large number
of cells which function as natural containers and retainers of
coffee fat and of the aromatic flavoring substances. In order to
render the soluble solids fully accessible, the resistance which
these cells offer to the extracting water must be overcome by
grinding so as to break open all of them. In this manner a grind is
obtained which will give a maximum removal of the heavy
extractives. But when all of the cells are broken, great
opportunity is offered for the escape of the caffeol, which is
further enhanced by the slight heating which usually accompanies
such fine grinding. So much caffeol escapes that even our most
expert cup-testers would experience difficulty in identifying
powdered coffees in a blind test. What cup-testers, in fact, use
powdered coffees for making their cup selections?
Consider powdered coffee, compared with freshly ground coffee of a
coarser grind. Neither the former nor its brew possesses the amount
of characteristic flavor or aroma, attributable to caffeol,
evidenced by the latter. The explanation of this is that the finer
the grind, the more readily accessible are the soluble constituents
of the coffee to the extracting water. Caffeol, however, in
addition to being water-soluble, is extremely fugacious, so that
when the grinding is carried to such a fineness that every cell is
broken, the greater part of the caffeol volatilizes before the
water comes into contact with it. It is therefore highly desirable
that a grind be used wherein all of the cells are not broken, but a
grind that is sufficiently fine to permit efficient extraction. In
the light of this knowledge, the grind advocated by King[384] seems
to be logical, for with it--though neither a maximum of the
non-volatile extractives nor a maximum of caffeol is obtained--an
all-round maximum of cup quality is procured.
The escape, upon grinding, of these volatile aromatic and flavoring
constituents which lend individuality to coffees, makes it
essential that the roasted beans be ground immediately prior to
extraction.
DIFFERENT METHODS OF EXTRACTION. The methods employed for preparing
the coffee drink may be classified under the general headings of
boiling, steeping, percolation, and filtration. True percolation is
the simple process known by the trade as filtration; but in this
classification, the term indicates the style of extraction
exemplified by the pumping percolator.
Boiled coffee is usually cloudy, due to the suspension of fine
particles resulting from the disintegration of the grounds by the
violence of boiling. The usual procedure in clarifying the
decoction is to add the white of an egg or some egg-shells, the
albumen of which is coagulated upon the fine particles by the heat
of the solution, and the particles thus weighted sink to the
bottom. Even this procedure, requiring much attention, does not
give as clear a solution as some of the other extraction procedures
employed. The conditions to which coffee is subjected during
boiling are the worst possible, as both grounds and solution
undergo hydrolysis, oxidation, and local-overheating, while the
caffeol is steam-distilled from the brew. Many persons, who have
long been accustomed to drinking the relatively bitter beverage
thus produced, are not satisfied by coffee made in any other way;
but this is purely a perversion of taste, for none of the
properties are present which make coffee so prized by the epicure.
[Illustration: CROSS-SECTION OF ROASTED COFFEE BEAN MAGNIFIED 600
TIMES]
[Illustration: COARSE GRIND UNDER THE MICROSCOPE]
Steeping, in which cold water is added to the coffee, and the
mixture brought up to a boil, does not subject the coffee to so
strenuous conditions. Local overheating and hydrolysis occur, but
not to so great an extent as in boiling; and most of the effects of
oxidation and volatization of caffeol are absent. However,
extraction is rather incomplete, due to lack of thorough admixture
of the water and coffee.
When coffee is to be made under the best conditions, the
temperature of the water used and of the extract after it is made
should not fluctuate. In the pumping percolator, as in the steeping
method, the temperature varies greatly from the time the extraction
is started to the completion of the operation. This is deleterious.
Also, local overheating of the infusion occurs at the point of
application of the heat; and because of the manner in which the
water is brought into contact with the coffee, the degree of
extraction shows inefficiency. Spraying of the water over the
coffee never permits the grounds to be completely covered with
water at any one time, and the opportunity offered for channeling
is excessive. The principle of thorough extraction demands that, as
the substance being extracted becomes progressively more exhausted,
fresh solvent should be brought into contact with it. In the
pumping percolator the solution pumped over the grounds becomes
more concentrated as the grounds become exhausted; so that the time
taken to reach the degree of extraction desired is longer, and an
appreciable amount of relatively concentrated liquor is retained by
the grounds.
[Illustration: MEDIUM GRIND UNDER THE MICROSCOPE]
The simplest procedure to follow is that in which boiling water is
poured over ground coffee suspended on a filtering medium in such a
manner that the extracting water will slowly pass through the
coffee and be received in a containing vessel, which obviates
further contact of the beverage with the grounds. The water as it
comes into contact with the ground coffee extracts the soluble
material, and the solution is removed by gravity. Fresh water takes
its place; so that, if the filter medium be of the proper fineness,
the water flows through at the correct rate of speed, and complete
extraction is effected with the production of a clear solution.
Thus a maximum extraction of desirable materials is obtained in a
short time with a minimum of hydrolysis, oxidation, and loss of
caffeol; and if the infusion be consumed at once, or kept warm in a
contrivance embodying the double-boiler principle, the effects of
local overheating are avoided. Also, with the use of an appropriate
filter, a finer grind of coffee can be used than in the other
devices, without obtaining a turbid brew. All this works toward the
production of a desirable drink.
There are several devices on the market, some using paper, and some
cloth, as a filter, which operate on this principle and give very
good coffee. The use of paper presents the advantage of using a new
and clean filter for each brew, whereas the cloth must be carefully
kept immersed in water between brews to prevent its fouling.
Contrivances operating on the filtration principle have been
designed for use on a large scale in conjunction with coffee urns,
and have proven quite successful in causing all of the water to go
slowly through the coffee without channeling, thus accomplishing
practically complete extraction. The majority of urns are still
operated with bags, of which the ones with sides of heavier
material than the bottom obtain the most satisfactory results, as
the majority of the water must pass through the coffee instead of
out through the sides of the bag. Greatest efficiency, when bags
are used, is obtained by repouring until all of the liquid has
passed twice through the coffee; further repouring extracts too
much of the astringent hydrolysis products. The bags, when not in
use, should not be allowed to dry but should be kept in a jar of
cold water. The urns provided with water jackets keep the brew at
almost a constant temperature and avoid the deterioration incident
to temperature fluctuation.
COMPOSITION OF BREWS. The real tests of the comparative values of
different methods of brewing are the flavor and palatibility of the
drink, in conjunction with the number of cups of a given strength
which are produced, or the relative strengths of brews of the same
number of cups volume. Chemical analysis has not yet been developed
to a stage where the results obtained with it are valuably
indicative. Caffeol is present in quantities so small that no
comparative results can be obtained. "Caffetannic acid"
determinations are practically meaningless. This compound is of so
doubtful a composition and physiological action, and the methods
employed for its determination are so indefinite as to
interpretation, as to render valueless any attempts at comparison
of relative percentages. The only accurate analysis which can be
made is that for caffein.
Much advertising emphasis has been placed on the small amount of
caffein extracted by some devices. What is one of the main reasons
for the consumption of coffee? The caffein contained therein, of
course. So that if one device extracts less caffein than another,
that fact alone is nothing in favor of the former. If the consumer
does not want caffein in his drink there are caffein-free coffees
on the market.
[Illustration: FINE-MEAL GRIND UNDER THE MICROSCOPE]
The coffee liquor acts on metals in such a manner as to lower the
quality of the drink, so that metals of any sort, and by all
means, irons, should be avoided as far as possible. Instead,
earthenware or glass, preferably a good grade of the former, should
be employed as far as possible in the construction of coffee-making
devices.
Of the various metals, silver, aluminum, monel metal, and tin (in
the order named) are least attacked by coffee infusions; and
besides these, nickel, copper, and well enameled iron (absolutely
free from pin holes) may be used without much danger of
contamination. Rings for coffee-urn bags should be made of tinned
copper, monel metal, or aluminum. Even if coffee be made in metal
contrivances, the receptacles in which it stands should be made of
earthenware or of glass.
Painstaking care should be given to the preservation of the
coffee-makers in a state of cleanliness, as upon this depends the
value of the brew. Dirt, fine grounds, and fat (which will turn
rancid quickly) should not be allowed to collect on the sides,
bottom, or in angles of the device difficult of access. Nor should
any source of metallic or exterior contamination be allowed to go
uneliminated.
_The Perfect Cup of Coffee_
Lovers of coffee in the United States are in a better position to obtain
an ideal cup of the beverage than those in any other country. While
imports of green coffee are not so carefully guarded as tea imports,
there is a large measure of government inspection designed to protect
the consumer against impurities, and the Department of Agriculture is
zealous in applying the pure food laws to insure against misbranding and
substitution. The department has defined coffee as "a beverage resulting
from a water infusion of roasted coffee and nothing else."
Today no reputable merchant would think of selling even loose coffee for
other than what it is. And the consumer can feel that, in the case of
package coffee, the label tells the truth about the contents.
With a hundred different kinds of coffee coming to this market from
nineteen countries, so many combinations are possible, that there is
sure to be a straight coffee or a blend to suit any taste. And those who
may have been frightened into the belief that coffee is not for them
should do a little experimenting before exposing themselves to the
dangers of the coffee-substitute habit.
Once upon a time it was thought that Java and Mocha were the only
worthwhile blend, but now we know that a Bogota coffee from Colombia,
and a Bourbon Santos from Brazil, make a most satisfying drink. And if
the individual seeker should happen to be a caffein-sensitive, there are
coffees so low in caffein content, like some Porto Ricans, as to
overcome this objection; while there are other coffees from which the
caffein has been removed by a special treatment. There is no reason why
any person who is fond of coffee should forego its use. Paraphrasing
Makaroff, Be modest, be kind, eat less, and think more, live to serve,
work and play and laugh and love--it is enough! Do this and you may
drink coffee without danger to your immortal soul.
If you are accustomed to buying loose coffee, have your dealer do a
little experimental blending for you until you find a coffee to suit
your palate. Some expert blends are to be found among the leading
package brands. But you really can not do better than to trust your case
to a first-class grocer of known reputation. He will guide you right if
he knows his business; and if he doesn't, then he doesn't know his
business--try elsewhere. Test him out along this line:
Let us reason together, Mr. Grocer. Let us consider these facts about
coffee: green coffee improves with age? Granted. As soon as it is
roasted, it begins to lose in flavor and aroma? Certainly. Grinding
hastens the deterioration? Of course. Therefore, it is better to buy a
small quantity of freshly roasted coffee in the bean and grind it at the
time of purchase or at home just before using? Absolutely!
If your grocer reacts in this fashion, he need only supply you with a
quality coffee at fair price and you need only to make it properly to
obtain the utmost of coffee satisfaction.
Some connoisseurs still cling to the good old two-thirds Java and
one-third Mocha blend, but the author has for years found great pleasure
in a blend composed of half Medellin Bogota, one-quarter Mandheling
"Java", and one-quarter Mocha. However, this blend might not appeal to
another's taste, and the component parts are not always easy to get. The
retail cost (1922) is about fifty cents.
Another pleasing blend is composed of Bogota, washed Maracaibo, and
Santos, equal parts. This should retail from thirty to thirty-five
cents. Good drinking coffees are to be had for prices ranging from
twenty-five to thirty cents. In the stores of one of the large chain
systems an excellent blend composed of sixty percent Bourbon Santos,
and forty percent Bogota is to be had (1922) for 29 cents. All these
figures apply, of course, to normal times.
If you are epicurean, you will want to read up on, and to try, the fancy
Mexicans, Cobáns, Sumatra growths, Meridas, and some from the "Kona
side" of Hawaii.
In preparing the perfect cup of coffee, then, the coffee must be of good
grade, and freshly roasted. It should, if possible, be ground just
before using. The author has found a fine grind, about the consistency
of fine granulated sugar, the most satisfactory. For general home use, a
device that employs filter paper or filter cloth is best; for the
epicure an improved porcelain French percolator (drip pot) or an
improved cloth filter will yield the utmost of coffee's delights. Drink
it black, sweetened or unsweetened, with or without cream or hot milk,
as your fancy dictates.
It should be remembered that to make good coffee no special pot or
device is necessary. Good coffee can be made with any china vessel and a
piece of muslin. But to make it in perfection pains must be taken with
every step in the process from roaster to cup.
Hollingworth[385] points out that through taste alone it is impossible
to distinguish between quinine and coffee, or between apple and onion.
There is something more to coffee than its caffein stimulus, its action
on the taste-buds of the tongue and mouth. The sense of smell and the
sense of sight play important rôles. To get all the joy there is in a
cup of coffee, it must look good and smell good, before one can
pronounce its taste good. It must woo us through the nostrils with the
wonderful aroma that constitutes much of the lure of coffee.
And that is why, in the preparation of the beverage, the greatest
possible care should be observed to preserve the aroma until the moment
of its psychological release. This can only be done by having it appear
at the same instant that the delicate flavor is extracted--roasting and
grinding the bean much in advance of the actual making of the beverage
will defeat this object. Boiling the extraction will perfume the house;
but the lost fragrance will never return to the dead liquid called
coffee, when served from the pot whence it was permitted to escape.
To recapitulate, with an added word on service, the correct way to make
coffee is as follows:
1. Buy a good grade of freshly roasted coffee from a responsible dealer.
2. Grind it very fine, and at home, just before using.
3. Allow a rounded tablespoonful for each beverage cup.
4. Make it in a French drip pot or in some filtration device where
freshly boiling water is poured through the grind but once. A piece of
muslin and any china receptacle make an economical filter.
5. Avoid pumping percolators, or any device for heating water and
forcing it repeatedly through the grounds. Never boil coffee.
6. Keep the beverage hot and serve it "black" with sugar and hot milk,
or cream, or both.
_Some Coffee Recipes_
When Mrs. Ida C. Bailey Allen prepared a booklet of recipes for the
Joint Coffee Trade Publicity Committee, she introduced them with the
following remarks on the use of coffee as a flavoring agent:
Although coffee is our national beverage, comparatively few cooks
realize its possibilities as a flavoring agent. Coffee combines
deliciously with a great variety of food dishes and is especially
adapted to desserts, sauces and sweets. Thus used it appeals
particularly to men and to all who like a full-bodied pronounced
flavor.
For flavoring purposes coffee should be prepared just as carefully
as when it is intended for a beverage. The best results are
obtained by using freshly made coffee, but when, for reasons of
economy, it is desirable to utilize a surplus remaining from the
meal-time brew, care should be taken not to let it stand on the
grounds and become bitter.
When introducing made coffee into a recipe calling for other
liquid, decrease this liquid in proportion to the amount of coffee
that has been added. When using it in a cake or in cookies, instead
of milk, a tablespoonful less to the cup should be allowed, as
coffee does not have the same thickening properties.
In some cases, better results are gained if the coffee is
introduced into the dish by scalding or cooking the right
proportion of ground coffee with the liquid which is to form the
base. By this means the full coffee flavor is obtained, yet the
richness of the finished product is not impaired by the
introduction of water, as would be the case were the infused coffee
used. This method is advisable especially for various desserts
which have milk as a foundation, as those of the custard variety
and certain types of Bavarian Creams, Ice Cream, and the like. The
right proportion of ground coffee, which is generally a
tablespoonful to the cup, should be combined with the cold milk or
cream in the double-boiler top and should then be scalded over hot
water, when the mixture should be put through a very fine strainer
or cheese cloth, to remove all grounds.
Coffee can be used as a flavoring in almost any dessert or confection
where a flavoring agent is employed.
On iced coffee and the use of coffee in summer beverages in general,
Mrs. Allen writes as follows:
ICED COFFEE. This is not only a delicious summer drink, but it also
furnishes a mild stimulation that is particularly grateful on a
wilting hot day. It may be combined with fruit juices and other
ingredients in a variety of cooling beverages which are less sugary
and cloying than the average warm weather drink and for that reason
it is generally popular with men.
Coffee that is to be served cold should be made somewhat stronger
than usual. Brew it according to your favorite method and chill
before adding sugar and cream. If cracked ice is added make sure
the coffee is strong enough to compensate for the resulting
dilution. Mixing the ingredients in a shaker produces a smoother
beverage topped with an appetizing foam.
It is a convenience, however, to have on hand a concentrated syrup
from which any kind of coffee-flavored drink may be concocted on
short notice and without the necessity of lighting the stove.
Coffee left over from meals may be used for the same purpose, but
it should be kept in a covered glass or china dish and not allowed
to stand too long. A coffee syrup made after the following recipe
will keep indefinitely and may be used as a basis for many
delicious iced drinks:
COFFEE SYRUP. Two quarts of very strong coffee; 3-1/2 pounds sugar.
The coffee should be very strong, as the syrup will be largely
diluted. The proportion of a pound of coffee to one and
three-fourths quarts of water will be found satisfactory. This may
be made by any favorite method, cleared and strained, then combined
with the sugar, brought to boiling point, and boiled for two or
three minutes. It should be canned while boiling, in sterilized
bottles. Fill them to overflowing and seal as for grape juice or
for any other canned beverage.
