To Prep: Drain cherries and then put on top of paper towels to get them as dry as possible. Line an 8-inch square pan with parchment paper and lightly spray with non-stick cooking spray.
Measure out the granulated sugar, corn syrup, and water directly into a medium saucepan. Stir until everything is well combined. Place the saucepan on the stovetop over medium heat and do not stir again. Allow the sugar mixture to heat up to 265°F (about 10 minutes). It will bubble, this is normal, and again, do not stir.
While the sugar mixture is boiling, prepare the egg whites in a heat-proof bowl. Beat the egg whites with an electric mixer until stiff peaks form. You could also use a stand mixer.
When the sugar mixture reaches 265°F, remove pan from heat. Carefully pour the hot sugar mixture into the egg white meringue, mixing with an electric mixer on low speed as you pour. Once all the sugar is mixed into the egg whites, continue to mix the divinity for about five minutes until it thickens and no longer looks glossy.
Stir in the cherries and pour the divinity mixture onto your prepared surface. Allow to set up for a few hours until you can cut and store.
