Frosting for Cake.
Whites of three eggs.
Three cups of powdered sugar.
Strained juice of a lemon.
Put the whites into a cold bowl and add the sugar at once, stirring it in thoroughly. Then whip with your egg-beater until the mixture is stiff and white, adding lemon-juice as you go on. Spread thickly over the cake, and set in the sun, or in a warm room to dry.
