Lo Soni Cake
Twenty-one pounds of powdered sugar, 13½ pounds of lard or butter; this must be rubbed well for fifteen minutes, and if made with cake machine will take eight or ten minutes; add 6 pints of eggs (rub them a few at a time), 3 quarts water or milk. Dissolve 2 ounces of ammonia in wet part of mixture, 1½ ounces of ground mace, 1 ounce of gelatine. Mix this all together. Next put 1 pound of egg nutrine or 2 teaspoonfuls of egg color; add 24 pounds of strong cake flour, with 1½ ounces cream of tartar. Mix this all together. Mix very light. This is baked in thin pound cake pans; each pan will hold from 7 to 9 pounds; fill three-quarters full, close lid down tight and set in cool oven in heat of about 330 degrees F. Baked, but still hot, take a good egg icing and cool it with some walnuts and sprinkle on top. This cake can be sold for 12 or 14 cents per pound, according to trade.
