Insert the popsicle sticks into the centers of each apple. Set them aside on a baking sheet lined with parchment paper.

In a small saucepan, bring the granulated sugar, black tea, and corn syrup to a boil over medium high heat. Continue heating the mixture, without stirring, until a candy thermometer inserted into it reads 300 degrees Fahrenheit. Add the red food coloring and stir until combined.

Remove from heat and quickly dip each apple in the hot syrup mixture, holding it by the popsicle stick, and turning to coat the apple in the mixture. If the syrup isn’t deep enough to coat the apple, use a metal spoon to help scoop and drizzle the mixture over the apple. After each apple is coated, place it back on the parchment paper and allow to cool until it hardens, (about 1 hour), before serving.
