44. In the cooking of mixtures containing eggs, no utensil proves quite so satisfactory as the double boiler, which has already been explained and illustrated. In fact, it is almost impossible to cook an egg mixture directly over the flame on account of the difficulty encountered in preventing the eggs from curdling. The low temperature at which cooking is possible in the double boiler makes it a comparatively simple matter to bring a mixture to the proper consistency without the formation of curds. Still, a certain amount of precaution must be taken even with a double boiler. If the degree of heat that is reached in this utensil is applied too long, the result will be no more satisfactory than when mixtures are exposed directly to the heat and cooked at a high temperature. While every effort should be made to cook mixtures containing eggs, such as custards or mayonnaise, so as to prevent curds from forming, occasionally they will form in spite of all that can be done. However, it is sometimes possible to remedy the matter by placing the vessel at once in cold water and beating the mixture rapidly with a Dover egg beater until the curds disappear. The cold water cools the mixture and prevents the formation of more curds, and the beating breaks up those which have already formed, provided they are not too hard.
45. In addition to the uses already mentioned, eggs have numerous other uses in cooking with which the housewife should be familiar. For instance, slightly beaten egg is used to a great extent to make crumbs or meal adhere to the surface of croquettes, meat, oysters, etc. that are to be sautéd or fried in deep fat, a coating of this kind preventing the food from becoming soaked with grease. In addition, egg is used to stick flour together for certain kinds of dough, such as noodles. Then, again, it is much used to puff up mixtures and produce a hollow space in them, as in popovers and cream puffs. While such mixtures do not require beating, spongy mixtures, such as omelets and sponge cakes, do. In these, eggs are an important factor, and they must be thoroughly beaten in order to incorporate the air in small bubbles and thus produce the desired texture.
SERVING OF EGGS
46. The manner of serving eggs depends, of course, on the way in which they are cooked. One point, however, that should never be overlooked, so far as eggs that are to be served hot is concerned, is that they should be served immediately upon being prepared, so that they will not have an opportunity to become cool before being eaten. This applies particularly to any spongy mixture, such as puff omelet and soufflé, as these dishes shrink upon standing and become less appetizing in both appearance and texture.
Several ways of serving soft-cooked eggs are in practice, but probably the most satisfactory way is to serve them in egg cups. In case cups are used, they should be heated before being placed on the table, as the heat that they retain helps to keep the eggs warm. The eggs may be removed from the shell into the cup and eaten from the cup, or the unbroken egg may be placed point downwards in the small end of the cup, a small piece broken from the broad end of the shell, and the egg then eaten from the shell through the opening made in it. If egg cups are not available, the eggs may be removed from the shell and served in small dessert dishes, which also should be heated.
Many egg dishes are made more attractive and appetizing by means of a garnish of some kind. Small strips or triangular pieces of toast, sprays of parsley, celery leaves, lettuce, and strips of pimiento are very satisfactory for this purpose. If no other garnish is desired, just a sprinkling of paprika adds a touch of color.
47. In connection with the serving of eggs it will be well to note that they have a tendency to adhere to china and to discolor silver. Therefore, in the washing of china and the cleaning of silver that have been used in the serving of raw or slightly cooked eggs, much care should be exercised. Dishes in which eggs of this kind have been served should first be washed in cool water in order to remove all the egg, and then they should be thoroughly washed in hot water. If the hot water is applied first, the heat will cause the egg to coagulate and cling to the dishes. Silver that comes in contact with eggs tarnishes or becomes discolored through the action of the sulphur that is found in them, just as it does when it is exposed to the air. Dark spots that appear on silver from this source may be removed by means of a good silver cleaner.
