Recipe Introduction
The frosting that sets up hard, at least in Arizona climate, is called Royal
Frosting. I use it on sugar cookies, too. It's almost like a candy topping.
Unlike some egg white-based frostings, you don't have to cook a syrup first.Royal Frosting (from Fannie Farmer Cookbook)

Mix all ingredients in a bowl. Add the boiling water.
Beat at high speed for 6 to 10 minutes until the frosting
is thick enough to stand in peaks.
