Mock Angel Cake ~ 1912

Set a cupful of milk in a saucepan of boiling water, and heat to a boiling point. Into a sifter put a cupful of flour, a cupful of sugar, three tablespoonfuls of baking powder, and a pinch of salt, all sifted together four times. Pour the cupful of hot milk onto the flour and stir until smooth. Fold in the well-beaten whites of two eggs,--do not stir or beat them in. Do not grease the tins or flavor the cake. Bake in a moderate oven. Ice with water icing made by sifting one cupful of powdered sugar, and adding water and flavoring until it will spread.
