Mrs. J. Gilbert, Evanston.
White Part. — One cup white pulverized sugar, one-half cup butter, one-half cup sweet milk, whites of four eggs, two and one-half cups flour, two heaping teaspoons baking powder, or one teaspoon cream tartar and one-half teaspoon soda. Stir butter and sugar together to a cream, and beat whites of eggs to a stiff froth, which are to be added the last of all ingredients, with the half cup of flour, which must contain the baking powder well mixed in the flour; season to taste. This is a very good recipe for delicate cake also.
Dark Part. — One cup brown sugar, one-half cup molasses, one-half cup sour milk, two and one-half cups flour, one level teaspoon soda dissolved in the milk and in the molasses, yolks of four eggs and one-half cup butter, to be rubbed well together with the sugar; add one-half teaspoon cinnamon, allspice and cloves.
Either of these make good cake used separately, or well mixed to represent marble.
Mrs. Frances M. Thatcher.
One-half cup sour cream, one-half cup butter, two and one-half cups flour, one cup white sugar, the whites of five eggs, two-thirds teaspoon soda; prepare another mixture, except substituting dark sugar for white, and the yolks instead of the whites; fill a tin with alternate layers of each and bake. .
