I have an awesome butter cream frosting recipe, but have wanted to try out Royal Icing. I have been concerned about the raw egg whites, but have found this recipe off http://www.allrecipes.com/ . It says that it yields 3 cups of icing.
3 tablespoons meringue powder
4 cups sifted confectioners' sugar
6 tablespoons water
Here's what you do:
Beat all ingredients at low speed for 7 to 10 minutes, or until icing forms peaks. Tip: Keep icing covered with a wet kitchen towel at all times. Icing can dry out quickly.
I plan on making sugar cookies with royal icing some time this week. We'll see how it goes!
