In the fifth way the sugar and eggs are beaten thoroughly over boiling water, then cooled before the melted shortening and dry ingredients are added. This method is used for Gennoise cake and some kinds of layer cakes. Care must be taken to insure the right consistency of cakes. The mixture should be fairly stiff. If too moist the fruit will sink to the bottom. For rich cakes the tins should be lined with paper, the paper coming a short distance above the tins, so that the cake is protected as it rises. For very rich fruit cakes, experience has shown that it is best not to grease the paper or tin. The cake is not so liable to burn, and the paper can be removed easily when the cake is done without injuring it. On the other hand, if tins are lined for sponge cakes or jelly-rolls, the paper should be greased. [Illustration] When making cakes in which baking powder, carbonate of soda, cream of tartar or tartaric acid are used, almost everything depends upon the handling, which should be as light and as little as possible. The more rapidly such cakes are made the better they will be. Two cooks working from the same recipe will often produce entirely different results, if one kneads her mixture as if it were household bread, while the other handles it with due lightness of touch. As soon as the baking powder or other rising medium is added to the mixture, the cake should be put into the oven as quickly as possible. Soda alone is never good in a cake where there is shortening, unless some substance containing acid is used along with it. Molasses is one of the substances containing acid. The greatest care and cleanliness must be exercised in all cake making; and accuracy in proportioning the materials to be used is indispensable. The flour should be thoroughly dried and sifted, and lightly stirred in. Always sift flour before measuring, then sift it again with the baking powder to insure a thorough blending. Good cakes never can be made with indifferent materials. Eggs are used both as an aerating agent and as one of the "wetting" materials. It is not economy to buy cheap eggs, for such eggs are small, weak, colorless, and often very stale. Eggs should be well beaten, yolks and whites separately, unless other directions are given. The yolks must be beaten to a thick cream and the whites until they are a solid froth. Sugar tends to improve the texture of cakes, and when cheap cakes are made, plenty should be used, provided that the cake is not made too sweet. It should be dissolved before being added to the fat and the flour. For best cakes, and all that are required of a light color, fine-grained sugar should be used. With coarse-grained sugar there is danger of producing specks which show on the cakes after baking, unless they have been made by the method of beating up the eggs and sugar together with a beater over hot water. This method will dissolve the grains of sugar.
