Icing (for Cake). Recipe No. 1.
Reading edition
Beat the whites of three eggs to a froth only (not until they are white); add gradually one pound of powdered sugar while you continue beating; this may be done in five minutes. Flavor with lemon or vanilla. Beating the egg stiff before the sugar is added makes the icing slow in drying. Ice the cake as soon as taken from the oven.
