Ingredients

1 box confectioners' sugar (1 pound) 

5 tablespoons meringue powder, or 2 large egg whites 

Preparation

In the bowl of an electric mixer fitted with the paddle attachment, combine sugar and meringue powder. Mixing on low speed, add a scant 1/2 cup water. For a thinner consistency, usually used for flooding, add more water. A thicker consistency is generally used for outlining and adding details. Mix until icing holds a ribbonlike trail on the surface of the mixture for 5 seconds when you raise the paddle.
