- 3 tablespoons meringue powder
- 4 cups sifted powdered sugar
- 1/2 cup water
- Gel food coloring
- Disposable plastic piping bags
Combine meringue powder, powdered sugar and water in a mixing bowl. Beat with an electric mixer fitted with a whisk attachment for 2 minutes. Check consistency. For “flooding” cookies, when the icing falls off the beater into the bowl, it should disappear within 5 to 8 seconds. If it “melts” into the rest of the icing faster than that, it is too thin; add more powdered sugar, a tablespoon at a time. If it takes longer than 8 seconds to disappear completely into the rest of the icing, add additional water, 1 tablespoon at a time. To color, separate icing into individual bowls and add a drop of food coloring; mix and add additional coloring as needed (icing will darken with time; black and red will require the most food coloring). Transfer icing to piping bags. An easy way to do this is to place the piping bag down into a drinking glass. Fold the top of the bag over the edge of the glass to open the bag. Spoon the icing down in. Close the open end of the piping bag with a rubber band or a twist tie. To eliminate air bubbles in the icing, hold the bag firmly and swing in a circular motion for 15 to 20 seconds. Cut the end of the piping bag off to create a very small opening. To ice cookies, pipe an outline around the outside of the cookie and fill in the inside with additional icing until it’s fully coated. This is called “flooding” the cookie. Use a toothpick to pop any air bubbles.
