This Alton Brown Royal Icing Recipe is a smooth and glossy frosting, which uses egg whites and granulated sugar. It’s a classic, foolproof recipe, ready in just 10 minutes.
Alton Brown Royal Icing Recipe Ingredients
- 2 1/2 cups plus 2 teaspoons granulated sugar
- 4 large egg whites, or 1/2 to 3/4 cup (106 to 158 grams) pasteurized carton egg whites
- 1/4 teaspoon cream of tartar
- 1/4 teaspoon kosher salt
How To Make Alton Brown Royal Icing Recipe
- Make superfine sugar: Place granulated sugar in a high-powered blender and blend for about 1 minute until very fine. Weigh out exactly 1 pound (454 grams) for the recipe.
- Mix the base: In a stand mixer bowl fitted with the paddle attachment, combine egg whites, cream of tartar, and salt. Beat on low until smooth.
- Add the sugar: With the mixer still on low, slowly stream in the superfine sugar. Once fully added, increase to medium-high speed.
- Whip the icing: Beat for about 4 minutes, until it reaches a thick, frosting-like consistency.
- Adjust consistency (optional): For a thinner icing, mix in a bit of water or rum until desired texture is reached.
- Add color (optional): Divide icing into bowls and mix in gel food coloring as desired.
- Store or use: Use immediately, or store in an airtight container overnight. Stir well before reusing if it separates.
