Royal Icing
Royal Icing is a stiff icing that is excellent for putting a gingerbread house together or
other projects. It works as a glue holding the pieces together. After gingerbread pieces
have cooled, the pieces may be assembled. Attach pieces using royal icing piped from a
pastry bag.Let royal icing harden at least 4 hours before attaching the roof or candies.
To attach candy, gum, cookies and other edible decorations use royal icing piped from a
pastry bag. The icing is edible, but very hard and crunchy. Keep royal icing covered
at all times until ready to use.
