To three pound flour, sprinkle a tea cup of fine powdered coriander seed, rub in one pound butter, and one and half pound sugar, dissolve three tea spoonfuls of pearl ash in a tea cup of milk, kneed all together well, roll three quarters of an inch thick, and cut or stamp into shape and size you please, bake slowly fifteen or twenty minutes; tho' hard and dry at first, if put into an earthern pot, and dry cellar, or damp room, they will be finer, softer and better when six months old.
