3/4 cup sugar 1/4 lb. marshmallows 1/4 cup milk 2 tablespoons hot water 1/2 teaspoon vanilla
Put sugar and milk in a saucepan, heat slowly to boiling-point without stirring, and boil six minutes. Break marshmallows in pieces and melt in double boiler, add hot water, and cook until mixture is smooth, then add hot syrup gradually, stirring constantly. Beat until cool enough to spread, then add vanilla. This may be used for both filling and frosting.
