Milk, 1 quart;
Chymogen, 1 dram;
Buttermilk, 1 pint.
I. Boil milk for five minutes.
II. Cool to temperature of 100° to 105° F.
III. Add chymogen (dissolved in ℥j of cold water) and let
stand for one hour at temperature of 100° to 105° F.
IV. Let drain through cheese-cloth for one and a half hours,
and then throw out the whey.
V. Press the curd through the colander twice, adding the
buttermilk as the curd is pressed through.
VI. Make up the quart by adding sterile water.
When the food is to be given to the baby, heat only enough to take off
the chill, as more vigorous heating will cause the curd to clump at the
bottom of the bottle in large curds.
If there is any clumping, shake the bottle well before giving to the
baby.
Never put the baby directly from a milk diet to a milk-albumen diet,
but give one intervening feeding of barley water before giving
milk-albumen diet.
