Ingredients
1 egg whites
1 1/2 c. 10X confectioners sugar
1/2 tsp cream of tartar (hardening agent)
1/2 tsp each peppermint and vanilla
Preparation
Beat egg white briefly and gradually add sugar, tartar and flavorings. Continue to beat until mixture reaches a smooth, creamy texture. If consistency is too runny, add more powdered sugar in 1/4 cup segments.
I like to double this recipe for initial house construction. Keep bowl covered with damp cloth or plastic wrap to delay hardening while using icing, or spoon icing into a pastry bag with star-shaped tip to apply icing more carefully to the house. You can even make icicles and patterns with the icing! Overall construction and decorating may require 2-4 batches.
