Good Sponge Cake
Beat together the yelks of ten eggs, with a pound of powdered white
sugar--beat to a stiff froth the whites of the eggs, and stir them into
the yelks and sugar. Beat the whole ten or fifteen minutes, then stir in
gradually three-quarters of a pound of sifted flour. Flavor it with a
nutmeg, or the grated rind of a lemon. Bake it as soon as the flour and
spices are well mixed in.
