While the chicken is cooking, make the sauce. Stir the 2 Tablespoons of cornstarch into 2 cups of water until there are no lumps remaining and they are fully combined. Bring to a boil: ½ cup soy sauce, 2 Tablespoons bourbon, ½ cup brown sugar, 1 teaspoon ground ginger, ½ teaspoon garlic powder, ¼ cup honey, and the 2 cups of water with the cornstarch in it. Boil for about 2 minutes, stirring frequently, until the sauce thickens.
