Ingredients
Vegetable oil cooking spray, for molds
1 cup sugar
2 tablespoons glucose or corn syrup
1/4 cup water
1 tablespoon plus 1 1/2 teaspoons citrus juice (such as lime, lemon, or pink grapefruit)
1 tablespoon citrus zest (such as lime, lemon, or pink grapefruit)
1 small drop gel-paste food coloring (such as green, yellow, or pink)
Preparation
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.
