This smooth, hard-drying icing is perfect for making decorations that last. It is also useful as a "cement" to fasten decorations together. Royal icing is edible, but not recommended for icing cakes.
Beat all ingredients until icing forms peaks (7-10 minutes at low speed with a heavy-duty mixer, 10-12 minutes at high speed with a hand-held mixer).
NOTE: Keep all utensils completely grease-free for proper icing consistency.
* For stiffer icing, use 1 tablespoon less water.
**When using large countertop mixer or for stiffer icing, use 1 tablespoon less water.
Makes 3 cups.
