DEVILLED TOMATOES

Mix together the mashed yolks of three hard-boiled eggs, a teaspoonful each of powdered sugar and made mustard, and a pinch each of salt and cayenne. Add three tablespoonfuls of butter and, gradually, three tablespoonfuls of vinegar or lemon-juice. Bring to the boil, add two eggs well-beaten, and cook in a double boiler until thick. Pour over fried or boiled tomatoes and serve; or serve with a [Maître d’Hôtel Sauce] made hot with mustard and cayenne.
