Mare'S Most Delicious Icing - cooking recipe

Ingredients

1/2 cup Crisco
1/2 cup butter or 1/2 cup margarine
1 cup granulated sugar or 1 cup brown sugar
3/4 cup hot milk
1 teaspoon vanilla

Preparation

beat for a full 10 minutes( very important) the following 3 ingredients: butter or margarine, crisco, granulated sugar (or use 1 cup packed brown sugar for a maple icing).
heat milk in microwave till very hot (not boiling).
while beating. add hot milk to sugar and butter mixture very slowly.(I mean about 1/8 of a cup at a time -- all the while beating it well --
after all of the milk has been beaten in, beat in vanilla extract.
this is delicious (the brown sugar icing is wonderful with chocolate cake especially good with butter pecan or spice cake).
