Royal icing dries hard and matte and is best for detailed piping. Glaze-style cookie icing is made from powdered sugar, milk and corn syrup; it sets firm enough to stack but stays softer and shinier.

Icing is thinned for flooding, stiffened for outlines, tinted with gel food coloring and left to dry for several hours.
