1 Pound (3-3/4 cups) powdered sugar, sifted if lumpy
1 to 2 large egg whites, or substitute 4 teaspoons packaged egg whites and 1/4 cup water
1 TSP almond extract, vanilla or lemon juice
Instructions
Mix all of the ingredients together using an electric hand mixer, until the icing is smooth and thin enough to be pressed through a pastry bag with a writing tip. Add more lemon juice, if necessary.
