Strawberry Custard Sauce

Place a small saucepan on the stove with 1 pint milk, the yolks of 2 eggs and 2 tablespoonfuls sugar; stir constantly until it comes to a boil; instantly remove from the fire, flavor with vanilla and set it away to cool; then stir 1 cup strawberries into it; beat the whites of the 2 eggs to a stiff froth and put it on top of the sauce. This sauce is excellent with strawberry shortcake. NOTE.--Any kind of fruit may be substituted for strawberries.
