Martha Stewart's Royal Icing
Yield: About 2 1/2 cups
Prep Time: 12 min
Perfect. This icing dries hard, making stacking easier.
Ingredients:
1 pound powdered sugar
5 Tablespoons meringue powder
1/2 cup water
liquid or gel-paste food coloring (optional)Directions:
1. In the bowl of an electric mixer fitted with the paddle attachment, combine sugar, meringue powder, and a scant 1/2 cup water on low speed. Beat until mixture is fluffy yet dense, 7 to 8 minutes.
2. To thin the icing for flooding (filling in areas with a thin layer of icing), stir in additional water, 1 teaspoon at a time. Test the consistency by lifting a spoonful of icing and letting it drip back into the bowl; a ribbon should remain on the surface for 5 to 7 seconds.
3. To tint icing, dip a toothpick or wooden skewer into food coloring, and gradually mix it in until the desired shade is reached.
Tips:

Is Cream of Tartar the same as Meringue Powder?

No! They are completely different. Meringue powder can be found in craft stores or baking supply stores.

Thank you so much for the reply! I will now be on the look out for Meringue powder before I make the icing.
Thanks again!

If you can’t find meringue powder, look for a recipe which calls for egg whites.
