Method
Using electric mixer, beat 3¼ cups powdered sugar and egg whites until thick and shiny, adding more powdered sugar by tablespoonfuls if mixture is too thin to spread, about 3 minutes. Add lemon juice. Divide icing into portions, if desired, and add different food coloring to each. Cover until ready to use.
