METHODS OF COOKING EXPLAINED
BOILING
There is an erroneous impression that articles cook faster when the water is boiling violently, but this is not the case; the ebullition is caused by the escaping steam, which is lost heat, and the water at this time is at 212° (except in high elevations), however fast or slow it may be boiling. If, however, a little sugar or salt is added to the water it increases its density, and the heat rises to 224° before the steam escapes. The heat can be raised also by covering the pot and confining as much of the steam as possible. Where violently boiling water is recommended, as for rice and green peas, the object is not greater heat, but to keep the grains and peas separated by the turbulence of the water. There is waste of fuel in unnecessarily fast boiling, and economy can be easily practised here, especially where gas is used, as the boiling point, once reached, can be maintained with but little heat. Where the juices and color are to be retained, the articles are put into already boiling salted water. The albumen on the surface is then at once coagulated and the juices shut in. Where the object is to extract tbe juices, as for soups, they must be cut into pieces so as to expose more surface, and put into cold water, and the heat of the water gradually raised to the sim-
