Store wrapped in cellophane bags, twist-tied shut, in a cool, dry place for up to 1 month.
Coat lollipop molds lightly with nonstick cooking spray. Place lollipop sticks in the molds.
Combine the sugar, water, and corn syrup in a large, heavy saucepan. Bring to a boil over medium-high heat.
Continue cooking until the mixture reaches 300 degrees F (hard-crack stage). Immediately remove the saucepan from the heat.
Add the candy flavoring and stir to combine.
Pour the mixture into a heatproof measuring container with a spout, or a candy funnel. Divide the mixture among the prepared molds.
Working quickly, add a drop of food coloring to each lollipop. Use a toothpick or wooden skewer to swirl the food coloring around. You can add more drops or different colors as desired.
Let the lollipops cool and harden, about 15 minutes, before removing them from the molds.
