To Prep
In a large bowl, combine chicken with marinade ingredients. Mix well and leave to marinade in the refrigerator for at least 1 hr.
To Cook
Heat up oil in a heavy-bottomed pan or wok. Coat chicken once through the marinade again and deep fry until golden brown. Remove and drain off excess oil on paper towels.
In a clean pan or wok, heat up oil and add in all the sauce ingredients. Stir constantly over medium heat until the sauce bubbles and thickens. The process may take about 5-8 mins. Toss in the fried chicken pieces and mix thoroughly until they are well coated with sauce. Dish out and garnish with white sesame seeds if desired. Serve with steamed rice.
