Cream a cupful of butter with two cupfuls of molasses, warming both slightly to enable you to do this; beat very light and add a teaspoonful of allspice with a tablespoonful of ginger. Sift a teaspoonful of soda through two cupfuls of flour twice, and stir in lightly, adding flour for a soft dough. Mould with floured hands into round cakes, handling as little as may be, and bake quickly.
