Dip half of each prepared butter cookie in chocolate mixture. Roll chocolate-dipped portion in finely chopped pecans. Place cookies on wire racks until chocolate is firm. NOTE: Melt-Away Butter Cookies call for a cookie gun to shape the dough. With a cookie gun, you can stamp out a wide variety of perfectly shaped cookies in a minimum of time, making this piece of equipment a practical investment for someone who does a lot of baking and entertaining. You'll find both electric and hand-pump models of cookie guns available in most kitchen shops or department stores. Most are constructed so that you can make mints, cheese straws, and canapes as well as cookies. Since the models differ in construction, follow the specific manufacturer's directions for assembling and loading the gun. ----
