Use none but the best materials for making cake. If you cannot afford to get good flour, dry white sugar, and the best family butter, make up your mind to go without your cake, and eat plain bread with a clear conscience.
There are no intermediate degrees of quality in eggs. I believe I have said that somewhere else, but it ought to be repeated just here. They should be, like Cæsar’s wife, above suspicion. A tin whisk or whip is best for beating them. The “Dover Egg-beater” is the best in the market. All kinds of cake are better for having the whites and yolks beaten separately. Beat the former in a large shallow dish until you can cut through the froth with a knife, leaving as clear and distinct an incision as you would in a solid substance. Beat the yolks in an earthenware bowl until they cease to froth, and thicken as if mixed with flour. Have the dishes cool—not too cold. It is hard to whip whites stiff in a warm room.
Stir the butter and sugar to a cream. Cakes often fail because this rule is not followed. Beat these as faithfully as you do the eggs, warming the butter very slightly if hard. Use only a silver or wooden spoon in doing this.
Do not use fresh and stale milk in the same cake. It acts as disastrously as a piece of new cloth in an old garment. Sour milk makes a spongy cake; sweet, one closer in grain.
Study the moods and tenses of your oven carefully before essaying a loaf of cake. Confine your early efforts to tea-cakes and the like. Jelly-cake, baked in shallow flat tins, is good practice during the novitiate. Keep the heat steady, and as good at bottom as top.
Streaks in cake are caused by unskilful mixing, too rapid or unequal baking, or a sudden decrease in heat before the cake is quite done.
Don’t delude yourself, and maltreat those who are to eat your cake, by trying to make soda do the whole or most of the duty of eggs. Others have tried it before, with unfortunate results. If curiosity tempt you to the experiment, you had better allay it by buying some sponge-cake at the corner bakery.
Test whether a cake is done by running a clean straw into the thickest part. It should come up clean.
Do not leave the oven-door open, or change the cake from one oven to the other, except in extreme cases. If it harden too fast on the top, cover with paper. It should rise to full height before the crust forms.
Except for gingerbread, use none but white sugar.
