Combine mashed potatoes with all remaining ingredients. Singe and remove all pinfeathers from an 8- to 9-pound goose. Rub the cavity and skin with a cut lemon and salt. Stuff and truss the goose.
Place on a rack in a roasting pan (breast side up), toss a cut clove of garlic and a stalk of celery with leaves into the pan, and roast in a preheated 350° oven for 18 to 20 minutes per pound. Prick the skin, around the wings and legs, with a fork to release fat. Baste occasionally with pan drippings.
When goose is tender and the skin brown and crisp, place on a heated platter and garnish with watercress. Serve with applesauce.
