168. Maître d’Hôtel Sauce.—Put eight spoonfuls of white sauce in a stewpan, with four of white stock or milk; boil it five minutes, then stir in two ounces of maître d’hôtel butter; stir it quickly over the fire until the butter is melted, but do not let the sauce boil after the butter is in; this sauce should only be made at the time of serving.
