COLOR-FIELD COOKIES

Steps:

• Prepare the glaze: Combine box of confectioners' sugar, corn syrup, lemon juice and 3 tablespoons warm water in a medium bowl. Stir with a fork to combine well, slowly adding water as needed to achieve the desired consistency. You should have 2 cups total. Test the glaze on a cookie as you go: If it doesn't spread out on its own to a smooth finish within 10 seconds, it is too thick and needs more water. If it runs off the edge of the cookie, it's too thin and needs more confectioners' sugar.
• Let glaze sit, tightly covered, until ready to use, stirring occasionally. The glaze will keep for at least a week in a small airtight container like a glass jar.
• Decorate the cookies: Pour about 1/3 cup glaze into a small, wide bowl. Starting with a light gel food coloring, mix in color until desired shade is reached. Holding a cookie by the edges, with the top-side down, dip into the glaze, moving the cookie around a bit to make sure it coats the whole surface. Gently shake the cookie from side to side to let the excess glaze drip off.
• Use a small offset spatula to stop the flow of icing, gently scrape cookie against edge of bowl, and flip the cookie over. Use the spatula to spread the icing to pop any air bubbles, and make sure it goes all the way to the edges. The glaze should quickly smooth out on its own. If not, thin it out a bit until it does. Use your fingers to wipe away any icing on the outside edges.
• Continue in this way until you have mixed nine different colors and coated 2 or 3 of the cookies in each color. Let dry completely, a few hours. Cookies will keep in an airtight container up to 3 days.
