Biscuit Cake.
Take eggs according to the size of the cake, weigh them, shells and all; then take an equal weight of sugar, sifted very fine, and half the weight of fine flour, well dried and sifted. Beat the whites of the eggs to snow; then put the yolks in another pan; beat them light, and add the sugar to them by degrees. Beat them until very light; then put the snow, continuing to beat; and at last add by degrees the flour. Season with lemon-peel grated, or any peel you like; bake it in a slow oven, but hot enough to make it rise.
