Beat an egg and add to it two-thirds cupful each of sugar, melted butter, and molasses. Add a cupful of milk in which a teaspoonful of soda has been dissolved, and sift in two and one-half cupfuls of flour with a teaspoonful of cream tartar. Add a tablespoonful each of lemon-juice and mixed spice, turn into a shallow pan, and bake for twenty minutes in a moderate oven.
