Remove skin from breasts of three partridges. Cut off breasts, leaving wing joints attached. Separate large from mignon fillets. Make five parallel slanting incisions in each mignon fillet, and insert in each a slice of truffle, having part of truffle exposed cut in points on edge. Beginning at outer edge of large fillets make deep cuts, nearly separating fillets in two parts, and stuff with Chicken Force-meat I or II. Arrange small fillets on large fillets. Place in a greased baking-pan, brush over with butter, add one tablespoon Madeira wine and two tablespoons mushroom liquor. Cover with buttered paper, and bake twelve minutes in a hot oven. Serve with SuprÍme Sauce.
