Dried beans and peas, cereals, and tough cuts of
meat will not cook tender so readily in hard water as in soft, but the
addition of a small amount of soda during the cooking of these foods
will assist in softening them.
Water is used in cooking chiefly for extracting flavors, as in the
making of coffee, tea, and soups; as a medium for carrying flavors and
foods in such beverages as lemonade and cocoa; for softening both
vegetable and animal fiber; and for cooking starch and dissolving sugar,
salt, gelatine, etc. In accomplishing much of this work, water acts as a
medium for conveying heat.
37. BOILING.--As applied to cooking, boiling means cooking foods in
boiling water. Water boils when its temperature is raised by heat to
what is commonly termed its _boiling point_. This varies with the
atmospheric pressure, but at sea level, under ordinary conditions, it is
always 212 degrees Fahrenheit. When the atmospheric pressure on the
surface of the water is lessened, boiling takes place at a lower
temperature than that mentioned, and in extremely high altitudes the
boiling point is so lowered that to cook certain foods by means of
boiling water is difficult. As the water heats in the process of
boiling, tiny bubbles appear on the bottom of the vessel in which it is
contained and rise to the surface.
