Butter a sheet of letter paper, place a boned bird on lower half of sheet, fold upper half over bird, bringing edges of paper together. Begin at edges, and fold over lower side and ends of paper three times. Place in a wire broiler, and broil ten minutes over a slow fire, being careful that paper does not catch on fire. Remove from case, place on slice of toast, season with salt, pepper, and batter. Garnish with thin slices of lemon and parsley. A breast of chicken, tenderloin of steak, or lamb chop may be cooked in the same way.
