In a heavy 6-quart casserole, combine the celery, onions, parsley and tarragon. Lay the oiled chicken pieces on top. Pour on the vermouth. Sprinkle with salt and pepper and a dash of nutmeg. Tuck the garlic cloves in and around the chicken pieces. Cover the casserole tightly with aluminum foil, then the lid. Bake 90 minutes without removing the lid.
