*Royal Frosting
BEAT 3 Tbsp. meringue powder, 1/2 tsp. cream of tartar and 6 Tbsp. warm water with electric hand mixer at high speed until blended. Slowly add 2 cups icing sugar on low speed until blended; beat on high speed about 5 minutes or until stiff peaks form.
COVER icing at all times to prevent hardening. To store several hours or overnight, place plastic wrap directly on surface of icing; refrigerate. Before using, beat with mixer until stiff. Makes about 2 1/2 cups.
