Stir well ; if the water still looks milky, add more hot water
or much of the curd will be left in the water ; if the curd is
made too hot it will be hard and crumbly. Draw the corners
of the strainer cloth together and let the whey drain out.
Then tie them ; hang the cloth over the short-armed rack
which should be near the sink, and let it drip without pressure
into the pan below. When dripping has ceased and there is
a firm ball of curd in the cloth, turn out into a bowl. If
stringy or so hard that it is a mass of crumbs, press it through
a strainer with a wooden masher. Season with salt and stir
in sufficient cream or melted butter to moisten it so you may
pack it smoothly into small cups ; — or shape it into small
balls. Vary the flavor by stirring in minced parsley, cress, or
pimientoes.
Cheese is a higlily concentrated protein food and should
be combined with milk, rice, bread or other starchy foods.
It is a substitute for meat and costs much less. A dish of
macaroni with milk and cheese is too rich to be served with
hearty meat, but combines well in a made over dish of fish
or meat, or as the chief dish at luncheon.
LESSON XI
EXPERIMENT WITH STARCH
If thin slices of raw potato are soaked in cold water, after a
while a sediment is found in the pan. This is starch, which
has dropped out of the cells which were cut by slicing. This
sediment may be purified and dried, and then it will be like
the pure starch of commerce.
Pure starch is a fine white powder and is found enclosed in
cells in the various grains, seeds, and vegetables. The starch
commonly used in cooking is made from potatoes and corn.
Wet a teaspoon of cornstarch with a little cold water.
It appears to mix with the water, but after standing a short
time the starch is found at the bottom of the bowl, and the
water is clear again, showing that it has not united with the
starch ; but by stirring this wet starch until a smooth paste
is formed, and pouring it quickly into boiling water, we find
that the membranes of the cell walls soften and burst ; the
starch grains swell and absorb the water ; and the fine powder
inside unites with the boiling water.
We learn from this experiment that cold water does not
affect starch; and that boiling water is absorbed by the
starch grains, causing them to swell and form a thick pasty
mass, which when cold is something like jelly. We call this
change in the starch, hydrating or gelatinizing the starch.
Starch is from the German word, starke, meaning *' stiff."
This experiment teaches us the first important principle
of mixing dry and Hquid ingredients and for boiling starchy
foods : Any starchy food in the form of a powder, like
flour or cornstarch, when it is to be used as a thickening,
should first be wet with a little cold liquid to form a
smooth paste. Then add more cold water until it is thin
126

enough to pour. Stir it quickly into rapidly boiling water,
and the grains will burst uniformly.
If boiling water be poured upon fine dry starch, the grains
are so compact it will not reach all of them. Some will burst
more quickly than others, some will not burst at all, and the
mass will be lumpy.
But all other starchy foods, like rice and other whole
grains, vegetables, tapioca, etc., should be put directly into
boiling water.
