Rita's Boiled Frosting

You may substitute brown sugar for white for a mapley" flavor. You can substitute 1 teaspoon of maple syrup for the vanilla if you wish."

Mix the sugar , corn syrup , and water in a small , heavy saucepan.

Insert a candy thermometer , partially cover pan and bring to a boil over moderate heat.

Remove cover and boil without stirring until the thermometer registers 240-242.

Just before syrup reaches the proper temperature , begin beating egg whites with an electric mixer until soft peaks form.

When syrup reaches the correct temperature , set mixer at high speed and pour syrup into whites in a slow thin stream.

Continue beating until glossy and firm enough to hold a shape.

Beat in vanilla.

Makes enough to fill and frost a 9 two layer cake".
