Wash and dry apples; if your apples have a wax coating, dip them in boiling water to remove the wax. (this is very important for making the candy stick to the apples)

Insert lollipop sticks into the top of each apple, about halfway down.

Line a baking sheet with parchment paper and set aside.

Combine the sugar, water, and corn syrup in a large pot. I like to use my Dutch oven for this.

Bring the mixture to a boil over medium heat.

Using a candy thermometer, cook the mixture until it reaches 300 degrees Fahrenheit (the hard crack stage).

Remove the mixture from heat and CAREFULLY stir in red food coloring. It may pop and splash - so be careful.

Carefully dip each prepared apple into the mixture, swirling to cover the entire apple.

Allow any excess candy mixture to drip back into the pan before moving the apples to the parchment-lined baking sheet.

Allow the apples to cool completely before serving.
