Citrus-Zest Lollipops

Lightly coat large or small round lollipop molds (hard candy) with cooking spray, and place lollipop sticks in grooves. Bring sugar, glucose, and water to a boil in a small saucepan over medium-high heat. Heat until a candy thermometer registers 300 degrees. Remove from heat, and carefully stir in citrus juice and zest and food coloring with a rubber spatula. (Mixture will steam and bubble when liquid is added. Be careful, and make sure zest is distributed evenly and not in clumps.) Transfer mixture to a liquid measuring cup, and let bubbles settle slightly, about 10 seconds.

Slowly pour mixture into prepared lollipop molds. Let cool, until lollipops harden, about 30 minutes. Remove lollipops from molds.
