2    Egg whites
1/2 ts Cream of tartar
2 c  Confectioners sugar
Food coloring

Using mixer, beat whites with cream of tartar until stiff. Gradually
beat in 1 cup of sugar. Beat 20 minutes. Beat in second cup of sugar;
beat 10 minutes more. During last few minutes of beating, add
coloring. While using cement, press transparent wrap directly on top
of frosting in bowl to prevent drying; lift wrap just long enough to
remove cement for each application.
