1. Marinate chicken in the mixture "A" in a small bowl for about 30 mins.
2. In a separate bowl, add all the ingredient B and mix. It's the batter we will use to fry. Dip the chicken pieces in the frying-batter and drop them in the oil for about 3 to 4 mins until nicely brown. Set aside.
3. In a skillet, heat 1/2 tbsp vegetable oil and add garlic. Fry until fragrant. Add all the rest of the ingredient C (soy sauce, sugar, wine or cooking sake, and ketchup) and fried-chicken and cook until they are hot and sauce thickens.
4. Transfer the chicken to a plate and sprinkle white sesame.
