Ingredients
4 cups confectioners' sugar, sifted
5 tablespoons pasteurized egg whites

Using an electric mixer on low, combine confectioners’ sugar, egg whites, and cream of tartar; beat on high until icing is whipped and opaque, about 2 minutes. Thin with water as needed to make a stiff but spreadable icing.
