The consistency may be thinned by adding a little water if necessary. Thicker icing may be used to outline cookies, and thinner icing may be used to "flood" or fill inside the outline. For the Christmas Tree Sugar Cookies, two to three drops of gel food coloring can be added after the mixture is smooth.

- 5 tablespoons meringue powder
- 1 one-pound box confectioners' sugar (about 4 cups)
