Sponge Cake

• Yolks 6 eggs.
• 1 cup sugar.
• 1 tablespoon lemon juice

Beat yolks until thick and lemon-colored, add sugar gradually, and continue beating, using Dover egg-beater. Add lemon-juice, rind, and whites of eggs beaten until stiff and dry. When whites are partially mixed with yolks, remove beater, and carefully cut and fold in flour mixed and sifted with salt. Bake one hour in a slow oven, in an angel cake pan or deep narrow pan.
