Cut the chicken into 1-inch pieces and place in a large bowl. Add garlic, whiskey, soy sauce, honey, and egg whites. Mix well and let marinate for 15 to 30 minutes.
Add cornstarch and toss until all chicken pieces are evenly coated.
Heat oil in a heavy bottom pot or cast iron skillet over medium-high heat until it reaches 350°F.
Fry the chicken in batches, making sure not to overcrowd the pan. Cook until crispy, golden brown, and cooked through. Remove chicken and place on a parchment lined baking sheet with a cooling rack to drain excess oil while staying crispy.
In a large skillet over medium heat, add the fried chicken. Pour the sauce ingredients over the chicken and toss to coat. Simmer for a few minutes until the sauce thickens slightly.
Sprinkle with sesame seeds and green onions. Serve immediately over rice and enjoy.
