Directions:
Cut 1/2 pound of cheese in very small pieces and add 1 ounce of fresh butter, 2 tablespoonfuls of fine bread-crumbs, 1 teaspoonful of prepared mustard, salt and pepper and a pinch of cayenne to taste. Mix well together to a smooth paste. Have ready some buttered toast; place on a dish, spread with the mixture and set in the oven until melted. Serve at once.
