Recipe: Old-Fashoned Sponge Cake

Two cups of sifted white sugar, two cups of flour measured before sifting, ten eggs. Stir the yolks and sugar together until perfectly light; add a pinch of salt; beat the whites of the eggs to a very stiff froth and add them with the flour, after beating together lightly; flavor with lemon. Bake in a moderate oven about forty-five minutes. Baking powder is an improvement to this CAKE, using two large teaspoonfuls.
