A knowledge of the proper temperature necessary to bring about this change is absolutely essential to any one who would cook eggs, and dishes which contain them, such as creams, puddings, etc., as they should be cooked. A great deal of the philosophy of cooking depends upon this knowledge, for nearly all kinds of meat, fish, oysters, milk, and other albuminous foods contain as one of their most valuable nutrients the substance known as albumen. When they are cooked with reference to this _alone_, we find that they are also done in the best-known way with reference to their other ingredients. Practically with our present kitchen appliances it is exceedingly difficult to maintain for half an hour a steady temperature of 160°, but excellent results may be obtained by the following method. SOFT-COOKED EGGS Pour enough boiling water into a saucepan to more than cover whatever number of eggs are to be cooked; then put in the eggs, and let them stand for ten minutes on the hearth or any place where the water will not lose its warmth too quickly. Remember that it is the heat in the water which is to do the cooking. The saucepan should remain uncovered. Practically this is an excellent way to do, for the amount of heat in the water will not fall below 160° Fahr. in the ten minutes, and that time is sufficient for it to penetrate to the center of the egg. Moreover, if the egg be forgotten, and remains in the water for a longer time, it will not become hard unless the temperature of the water be raised. Theoretically an egg should be cooked at 160° Fahr., but practically this would involve a considerable waste of time and necessitate the use of a thermometer. Almost the same result is obtained in an easy and convenient way by the above method, although it is not an exact one. The proportion of boiling water for each egg which will insure cooking in the time given is one pint, but somewhat less will do if many are to be cooked; for instance, eight eggs will do in six pints, as comparatively less heat is lost in warming the pan. POACHED OR DROPPED EGGS From a thin, even slice of home-made bread cut out a round piece with a biscuit-cutter; toast it a delicate brown.
