Heat about 2 tablespoons of oil in a skillet, then add chicken and let it rest for about 30 seconds before stirring. Cook for 4-5 minutes or until chicken has been fully cooked.
While the chicken is cooking, whisk together the bourbon, soy sauce, ketchup, apple cider vinegar, chicken stock, cornstarch, and brown sugar. Set aside.
Quickly stir in garlic, ginger, and white pepper into the skillet with chicken and continue cooking for another 2-3 minutes.
Pour the sauce mixture over the chicken and bring to a boil. Turn the heat down to low and simmer for 3-5 minutes or until sauce thickens. Add red pepper flakes and adjust thickness with broth if desired. It will thicken as it cools.
Sprinkle with sesame seeds and green onions and serve immediately over rice.
