Sift two pounds of flour into a deep pan, and rub into it three quarters of a pound of butter; then mix in a pound of common white sugar powdered; and three table-spoonfuls of the best white ginger. Having beaten four eggs very light, mix them gradually with the other ingredients in the pan, and add a small tea-spoonful of pearl-ash melted in a wine glass of sour milk. Stir the whole as hard as possible. Flour your paste-board; lay the lump of dough upon it, and roll it out into a sheet an inch thick; adding more flour if necessary. Butter a large shallow square pan. Lay the dough into it, and bake it in a moderate oven. When cold, cut it into squares. Or you may cut it out into separate cakes with a jagging iron, previous to baking. You must be careful not to lay them too close together in the pan, lest they run into each other.
