Combine egg whites (at room temperature) and cream of tartar in a large mixing bowl. Beat at medium speed of electric mixer until frothy. Gradually add sugar; beat well. Beat 5 to 7 minutes or until frosting is stiff.
Note: Paste food coloring may be added to tint frosting to desired shades. Frosting dries quickly; keep container covered with a damp towel.
