Ingredients
5 tablespoons meringue powder
1 pound (4 cups) confectioners' sugar, plus more if needed
Scant 1/4 cup water, plus more if needed
Preparation
With an electric mixer on low speed, beat confectioners’ sugar, meringue powder, and the water until smooth, about 7 minutes. If icing is too thick, add more water, 1 teaspoon at a time; if too thin, beat icing 2 to 3 minutes more, or add more sugar, 1 tablespoon at a time. Use immediately, or store in an airtight container at room temperature up to overnight; stir until smooth again before using.
