Mix all the ingredients in Frying Batter in a bowl until well combined, stir a few times to make sure there are no lumps and the batter is smooth. Add the chicken into the batter, stir to evenly coat with the batter.
Heat 2 to 3 inches (5 to 7.5 cm) of the oil in a wok or a stockpot to 350°F (175°C) for deep-frying. Gently drop the chicken into the oil and loosen them up immediately with a spatula to prevent the chicken from clumping together. Deep-fry the chicken to golden brown.
As soon as the Sauce thickens, add the fried chicken into the wok or skillet. Stir continuously until all the ingredients are well coated with the sauce. Dish out, garnish with the white sesame, and serve immediately with steamed rice.
