1/2 cup vegetable shortening
1/2 cup margarine
1 teaspoon vanilla extract or flavoring
4 cups confectioners' sugar
2 tablespoons milk* (or water)
Cream margarine and shortening. Add vanilla extract. Gradually add sugar, one cup at a time, beating well. Scrape sides of bowl often. Add milk and beat at medium speed until light and fluffy.
Keep icing covered with a damp cloth until cake is iced, or keep in fridge in an airtight bowl for up to 2 weeks.
Bring to room temperature and re-whip before using.
Yield" 3 cups
For Chocolate icing: add 3/4 cup cocoa or 3 squares of unsweetened chocolate, melted; add an additional 1 -2 tablespoons milk.
Hint: Milk makes the icing "crusty"; water will keep the icing soft. You can also add 3-4 tablespoons light corn syrup to make it spreading consistency.
Pineapple flavoring is also excellent.
Note: For fancy cake decorating!
