Egg Whites in Action: Royal Icing

Royal icing being mixed in a stand mixer using the paddle attachement

Royal icing is a hard white icing made from egg whites, confectioner's sugar, and sometimes an acid such as lemon juice. It's used for decorating cakes and cookies, and with the addition of solid fat and gum, it becomes gum paste. 

 

Essential Royal Icing Tips:

  • If mixing in a stand mixer, use the paddle, not the whisk, and mix on low speed.
     
  • Royal icing recipes are not interchangeable. Recipes made with fresh whites, meringue powder, or dried egg whites are all used for different purposes.
     
  • Dried egg white powder must first be rehydrated in order to make royal icing. Be patient - they take a while to hydrate. And they smell pretty bad.
     
  • To avoid lumps, double-sift the confectioner's sugar before proceeding with the recipe.

Ingredients:

  • 150g Egg whites
  • 907g Confectioner's sugar, sifted

  • 24g Vegetable shortening

  3. Add the remaining confectioner's sugar to the egg whites. Beat on low speed until the sugar is saturated. Scrape the bowl, and mix on low-medium speed to medium stiff peaks.
     
  4. Add the Tylose powder and mix until the mixture reaches a clay-like consistency.

  8.  Wrap the paste in several layers of plastic wrap and refrigerate overnight before using. The paste can also be frozen indefinitely as long as it is wrapped very well.

Notes on Gumpaste from Chef Mark Seaman

In the case of gum paste, consistency will vary from decorator to decorator.  I happen to like my gum paste on the firmer side so I take my royal base just a little further than most.  This is so I can have more control over the position of the individual flower petals during processing. Unlike royal icing that I’d use for, say, piping a shell border on a fondant cake that I’d make with meringue powder, I would only use shelled whites for gum paste to ensure a better structure.
