3 3⁄4 cups (1 pound) confectioners' sugar
4 teaspoons powdered egg whites
1⁄2 cup water
1 tablespoon lemon juice
1 teaspoon vanilla extract
Food coloring (optional)
Directions
In a large bowl beat the confectioners’ sugar, egg whites, water, lemon juice, and vanilla extract with an electric mixer at medium speed for 1 to 2 minutes. Scrape the bowl once or twice, then increase the speed to high and beat until it holds stiff peaks, about 3 minutes. Add food coloring, if desired. Transfer the icing to a piping bag. If the icing is too thick to pipe, add water a few drops at a time to thin it. Pipe decorations onto cookies as desired.
