- Vegetable oil cooking spray, for molds
- 1 cup sugar
- 2 tablespoons glucose (<a href="http://wilton.com" target="_blank">wilton.com</a>) 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)
- Lightly coat large or small round lollipop molds (hard candy; candylandcrafts.com) with cooking spray, and place lollipop sticks (candylandcrafts.com) 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.
Lollipops can be stored in an airtight container for up to 3 days.
