2 pounds sugar.
½ pound glucose.
⅜ pound butter.
¾ pint water.
Put sugar, glucose and water in kettle on hot fire, stir until it
boils, wash down sides of kettle, then put cover on until it steams
well, remove cover and put thermometer in and cook to about 300,
then set kettle off the fire and put in the butter, stirring it
through the batch thoroughly, then put the kettle back on the fire,
and you must now stir it constantly; but before you put the butter
in it should not be stirred. Just before you put in the butter, take
out the thermometer, as it is less trouble to stir the candy with
the thermometer out, and it does not need to be cooked to any exact
degree. In putting in the butter, you reduce the temperature of the
batch about fifteen degrees, and it is necessary to cook it, after the
butter is put in, up to about the point it was before; but you will
have no trouble with this, and as soon as it boils up good and hard and
commences to turn color a little, drop some off the spoon very quickly
in cold water, and if it forms a mass of threads in the water it is
done. Be very sure to stir this well after the butter is in it or it
will stick. When done, set off the fire and add a good teaspoonful of
lemon extract, stir it in well and if you have a funnel, pour it in
the funnel, and drop on greased slab in wafers, which is the nicest
way to make this butterscotch; or you may pour the whole batch, if you
wish, on the greased slab, putting your bars on edge of slab to keep it
from running off, and let it run over as large a surface as possible,
as the thinner it is, the nicer it will be. Mark it in squares, but
do so very quickly, as it does not take it long to harden; and always
remember this: that you must take your spatula or a long butcher knife,
and loosen the whole batch thoroughly from the slab before it gets
perfectly cold, as then it will not stick when cold and also loosen the
wafers. Your slab must be well greased before pouring this on, but no
matter how well you grease it, if you allow the candy to get perfectly
cold before loosening it, you will find it will stick somewhat. In
loosening this candy before it gets cold, we do not mean to take it off
the slab, but just to simply run something under and loosen it, letting
it remain on the slab afterward, and you will find that it does not
stick.
