Royal Icing is used to make flowers, lace, and other decorations in advance. It’s also great for decorating cookies and used to make gingerbread houses. It sets up hard and dries very quickly, so it must be kept covered when not in use. Make sure all utensils, bowls, and storage containers are clean and grease-free by washing in hot, soapy water and wiping with clear vinegar. Any residual grease will break down the icing.
3 tablespoons meringue powder
1 pound powdered sugar
5-6 tablespoons warm water
Mix all ingredients at low speed for 7-10 minutes. This is important. If the icing isn’t mixed enough then it won’t hold its shape. Also, be careful not to let it get too thin. Just a little bit of water will make a big difference in this icing. Start off with just 5 tablespoons of water, then gradually add more if necessary after beating for at least 7 minutes.
