Yellow Royal Icing
- 7 1/2 teaspoons meringue powder
- 2 cups confectioners' sugar
- 3 to 6 tablespoons water
- Lemon-yellow gel-paste food coloring
With an electric mixer on low speed, beat meringue powder, sugar, and 3 tablespoons water until smooth, about 1 minute. Add more water, 1 tablespoon at a time until the mixture is the consistency of honey. Add food coloring until desired color is reached. Transfer to a pastry bag fitted with a small plain round tip (such as Ateco #2). Use immediately.
