1/2 cup solid vegetable shortening
1/2 cup (1 stick) butter or margarine softened
1 tsp. flavoring or your choice (I love vanilla and almond)
4 cups sifted confectioners' sugar
3 tablespoons milk
Cream shortening and butter or margarine with a mixer. Add flavoring then add sugar, one cup at a time, beating well on medium speed. When all sugar has been mixed in, icing will appear dry. Add milk and beat at medium speed until light and fluffy (you may need to adjust amount of milk if it still seems to dry). Keep bowl covered with a damp cloth until ready to use. Refrigerate any leftovers.
