Season a loin of pork and roast for two hours and a half, basting often with the drippings and hot water. About an hour before it is done, add peeled sweet potatoes cut in halves and sprinkle with sugar. Fifteen minutes later, add red cooking apples cored but not peeled. Bake until all are done, basting frequently. Thicken the drippings with flour for a gravy and serve separately.
