Orange layer cake
Cream three tablespoonfuls of butter with two cupfuls of sugar, add the beaten yolks of five eggs, the juice and half the grated rind of an orange, and three cupfuls of flour—or enough for a batter—sifted with two teaspoonfuls of baking-powder. Last of all, fold in the stiffened whites of three eggs. Bake in layer tins.
