This pair of recipes came out of the need to provide safe food for my family at two different events. The first was for Zax's class Gingerbread Party. The sign-up sheet came home, asking for parents to provide icing or decorations for the party. I signed up for icing and then chatted with the teacher the next morning. I know that oftentimes, Royal Icing is used for gingerbread houses because it dries very hard and strong, making a good "glue" for the houses. Was the recipe going to involve egg?
