SPONGE CAKES AND THEIR PREPARATION
METHOD OF PROCEDURE
39. With the ingredients and utensils gathered and prepared, the mixing of the cake may be begun at once. The method of mixing depends entirely on the kind of cake that is being made, sponge cake involving a different procedure from b.u.t.ter cake. These methods should be thoroughly mastered, so that there will be no danger of confusing them and so that the recipe will not need to be referred to constantly during the mixing of the cake. When an ingredient that is not usually included in the ordinary b.u.t.ter or sponge cake is found in the recipe, the way in which this ingredient is added to the mixture should be carefully noted, so that no mistake will be made.
40. NATURE OF SPONGE CAKE.--A true sponge cake contains nothing besides eggs, sugar, flour, and flavoring material. The eggs, sugar, and flour are used in equal amounts, the eggs and sugar being about the same by weight or measure and the flour half as much by weight. For instance, a successful sponge cake can be made with a cupful each of eggs, sugar, and flour. To these ingredients the juice of 1/2 lemon is usually added, and sometimes the grated rind of the lemon is used also. The simple variation in sponge-cake mixtures is the addition of liquid, which is usually water, sometimes cold and sometimes hot. In the true sponge cake, eggs supply all the leavening, but it is possible to economize in the number of eggs by using leavening of some other kind, such as soda and cream of tartar or baking powder. The texture of a sponge cake in which leavening other than eggs is used is not so good as that of the true sponge cake, but if this leavening is used discreetly, it is possible to decrease the number of eggs somewhat without sacrificing too much in texture. However, it is useless to try to make a good sponge cake with fewer than three eggs, for the other ingredients--flour, sugar, leavening, and liquid--are not sufficient to produce a delicious cake.

41. COMBINING THE INGREDIENTS.--The ingredients required for a true sponge cake and the utensils used in making such a cake are shown in Fig. 3. As will be observed, both the utensils and the materials are so placed on the table in front of the one who is to make the cake that the work may be performed with the least amount of effort.
[Ill.u.s.tration: FIG. 4, Using the rotary egg beater.]
If the whole eggs are to be used, break them into the mixing bowl and beat them with a rotary egg beater, as shown in Fig. 4, until they are thick and lemon-colored. In case only the whites are to be used, beat them with an egg whip on a flat dish or in a large bowl until they are stiff. To the beaten egg, add the sugar a little at a time, as shown in Fig. 5, beating it into the egg with the rotary beater.
[Ill.u.s.tration: FIG. 5, Beating in the sugar.]
Either granulated or pulverized sugar may be used, but pulverized is the better of the two, because it is lighter. When the sugar is added at this time, sift the flour several times, and, as in Fig. 6, add it last, folding it into the mixture with a wire egg whip. However, if it is desired to do so, the sugar and flour may be sifted together and added at the same time, or both the sugar and flour may be sifted separately and then added to the eggs alternately. Then add the flavoring and, if liquid is to be used, put it in at this time. In case leavening is supplied, sift it in with the flour. The mixture is then ready for the pan. Place the ungreased pan conveniently on the table and then, as shown in Fig. 7, pour the mixture from the bowl into it. Sc.r.a.pe the sides of the bowl well, so that there will be no more waste than is necessary.
[Ill.u.s.tration: FIG. 6]
42. BAKING SPONGE CAKE.--As soon as the mixture has been poured into the pan, set it in a moderate oven to bake. The temperature should be about 300 degrees Fahrenheit when the cake is put into
[Ill.u.s.tration: FIG. 7]
In putting the cake into the oven, set it on the lower rack, as here the mixture will be in a position to come up with the heat of the oven, which, as is known, has a general tendency to rise. If it is placed on the top rack where the heated air is necessarily pa.s.sing down toward the outside walls because of the circulation that is established, there will be a certain amount of pressure on top of the cake which will prevent it from rising. Allow the cake to remain on the lower rack until it has risen to its fullest extent, and then, if necessary, remove it to the top rack for browning.
[Ill.u.s.tration: FIG. 8]
43. Several tests to determine whether sponge cake is ready to remove from the oven can be applied. One of these consists in observing the cake in the pan. After it has risen as much as it will rise, a small amount of shrinkage will, as shown in Fig. 8, loosen the cake from the sides of the pan. Another test, which is known as the finger test, consists in making a depression in the center of the cake. If the cake is baked sufficiently, it will spring back to fill the depression, but if it is not done, the depression will remain.
[Ill.u.s.tration: FIG. 9]
44. REMOVING SPONGE CAKE FROM PAN.--When sponge cake is taken from the oven, it requires different treatment from that of b.u.t.ter cake. Instead of removing it from the pan immediately, turn it upside down on a cooler to sweat, as shown in Fig. 9. Allow it to remain in this way until it has shrunken sufficiently from the pan, and then lift off the pan. If necessary, the cake may become completely cold before the pan is taken from it. Close adherence to these directions will prevent any trouble that may arise in removing sponge cake from the pan.
RECIPES FOR SPONGE CAKE AND ITS VARIATIONS
45. PLAIN SPONGE CAKE.--The ideal proportions for a sponge cake are given in the accompanying recipe and upon these proportions the other recipes are based.
PLAIN SPONGE CAKE
4 eggs 1 c. sugar 1 c. flour Juice and rind of 1/2 lemon
Beat the eggs until they are thick and lemon-colored. Add the sugar gradually and continue to beat. Sift the flour several times and fold into the mixture. When the ingredients are thoroughly mixed, add the grated rind and the juice of the lemon, pour into a sponge-cake pan, and bake.
46. COLD-WATER SPONGE CAKE.--The accompanying recipe is a slight variation from the true sponge cake, for it contains leavening other than eggs and a small amount of cold water. No difficulty will be experienced in making a cake according to this recipe if the directions are carefully followed.
COLD-WATER SPONGE CAKE
3 eggs 1-1/2 c. sugar Rind and juice of 1 lemon 1/2 c. cold water 2 tsp. baking powder 1-1/2 c. flour
Beat the eggs until they are thick and lemon-colored. Add the sugar gradually and continue beating. Grate the yellow part from the lemon rind and add it with the juice. Pour in the cold water, continuing to beat. Sift in the baking powder with the flour and add to the egg mixture. Pour into a sponge-cake pan and bake.
47. HOT-WATER SPONGE CAKE.--Hot water and leavening in the form of soda and cream of tartar are used in the accompanying recipe for sponge cake. The texture is not just the same as that of a plain sponge cake, but if the recipe is carefully followed an excellent cake will be the result.
HOT-WATER SPONGE CAKE
4 eggs 2 c. flour 1-1/2 c. powdered sugar 1/2 tsp. soda 1-1/4 tsp. cream of tartar 1/4 c. hot water 1 tsp. vanilla
Beat the eggs with a rotary beater until they are thick and lemon-colored. Sift the flour, powdered sugar, soda, and cream of tartar together several times. Sift these into the eggs and continue beating.
When all of the dry ingredients have been added, pour in the boiling water, flavor with the vanilla, and pour into a sponge-cake pan and bake.
48. ORANGE SPONGE CAKE.--Sponge cake is delicious when it is flavored with orange. No leavening except the eggs is used in the recipe for cake of this kind. Lemon may be used in place of orange and 1/2 cupful of finely chopped nuts may be added.
ORANGE SPONGE CAKE
4 eggs 1 c. granulated sugar 3/4 c. flour 2 Tb. orange juice 1/2 tsp. orange extract
Beat the eggs with a rotary beater until they are light and lemon-colored. Add the granulated sugar gradually. Sift into this the flour, and continue the beating until all are mixed. Add the orange juice and extract, pour into a sponge-cake pan, and bake.
49. SUNs.h.i.+NE CAKE.--Nothing more delicious in the way of cake can be made than suns.h.i.+ne cake. It is especially nice to serve with a frozen dessert of some kind, for it is not too rich and it is attractive in color.
SUNs.h.i.+NE CAKE
6 eggs 1/3 tsp. cream of tartar 1 c. sugar 3/4 c. flour 1 tsp. lemon juice 1 tsp. vanilla
Separate the eggs. Beat the yolks with a rotary beater until they are thick and lemon-colored. Beat the egg whites until they are foamy, add the cream of tartar, and continue beating until they are dry. Fold the sugar into the egg whites and then fold the yolks into this mixture.
Sift the flour several times and add it. Add the lemon juice and vanilla, pour into a sponge-cake pan, and bake.
50. ANGEL CAKE NO. 1.--A variety of sponge cake in which only the egg whites are used is known as angel cake. Some persons hesitate to make cake of this kind because of the number of eggs it takes, but usually the yolks that remain can be put to very good use and so the cake is no more expensive than most others.
ANGEL CAKE No. 1
1 c. flour 1 c. powdered sugar 10 egg whites 1/2 tsp. cream of tartar 1 tsp. vanilla
Sift the flour and powdered sugar together four or five times in order to make them very light. Beat the egg whites with a whip until they are foamy. Add the cream of tartar, and continue beating until they are stiff enough to heap up in a mound and stay this way. Sift the mixture of flour and sugar a little at a time into the egg whites and continue beating until all is added. Flavor with the vanilla, place in a sponge-cake pan with a tube in the center, and bake in a very moderate oven.
51. ANGEL CAKE NO. 2.--If a slightly larger cake than the first angel-cake recipe will make is desired, the accompanying recipe should be followed. Its texture is practically the same as that of the other cake.
ANGEL CAKE No. 2
1-1/4 c. flour 1-3/4 c. powdered sugar 12 egg whites 1 tsp. cream of tartar
Sift the flour and sugar separately four or five times. Beat the egg whites until they are foamy and add the cream of tartar, continuing to beat until they are stiff. Add the powdered sugar gradually, continuing the beating. When all this has been added, sift in the flour, and fold it in with as light a motion as possible. Pour into a sponge-cake pan with a tube in the center, and bake in a very moderate oven, raising the temperature slightly at the end.
