Two simple cookie-decorating techniques?flooding and flocking?can transform plain sugar cookies into distinctive confections suitable for any occasion, from birthday parties to anniversary celebrations. Flooding is the process of coating a cookie with royal icing. To flood a cookie, use a pastry bag fitted with a small round tip, and follow the outline of the cookie. Leave some space along the edge for spillage, then fill in the outline with icing. To close empty spaces, push icing in place with a clean toothpick, and use a damp paper towel to wipe away any mistakes. To create a simple design of your choice, such as polka dots, use a different color icing to pipe the design onto the cookie. For a blended effect, decorate while the foundation is still wet. But if you don't want the colors to bleed, let the icing dry for a day.
Flocking is decorating with tinted sugar?an easy way to add color and texture to cookies. Use sanding sugar, which is available in a range of grains, for a sparkling effect. To apply sanding sugar, place the cookie on waxed paper, and sprinkle sugar over the top of the cookie. Let it dry for 1/2 hour before shaking off excess sugar, and for several hours before brushing away stray crystals
