Royal Icing

1 c powdered sugar

3/4 tsp meringue powder

1 1/2 tbsp warm water

food coloring, if desired

Combine powdered sugar and meringue powder. Add food coloring to water (color will become washed out when combined with powdered sugar, so make color strong). Add to powdered sugar mixture. Beat on high speed for 10-12 minutes until icing holds stiff peaks. Place in a pastry bag and pipe designs on cookies.
