New York Gingerbread
1 cup butter (scant)
1½ cups flour
2 tablespoons yellow ginger

Cream the butter, and add flour gradually, mixed and sifted with ginger. Beat the yolks of the eggs until thick and lemon-colored, and add sugar gradually. Combine mixtures, add whites of eggs, beaten until stiff, and sift over baking powder. Beat thoroughly, turn into a buttered deep cake pan, and bake one hour in a moderate oven.
