In a medium bowl, sprinkle the unflavored gelatin over the cold water. Let it sit for 5-10 minutes to bloom.

Lightly coat a 9x13 inch baking dish with non-stick spray, wiping away excess with a paper towel.

In a saucepan, heat the boiling water, 2 cups of sugar, and corn syrup over medium heat until the sugar is completely dissolved. Remove from heat.

Pour the hot sugar syrup over the bloomed gelatin and whisk gently until completely melted and smooth.

Add the Kool-Aid packet and whisk gently until the color is uniform.

Pour the mixture into the prepared baking dish and refrigerate for 2 to 3 hours until completely firm.

Peel the gummy slab from the dish and use an oiled knife to cut into 1/4-inch strips. Twist two strips together to form ropes.

Mix 1 cup sugar with citric acid. Roll the twisted ropes in the sugar mixture to coat, then let sit at room temperature for 12-24 hours to cure.
