Korean Fried Chicken is considered delicious and crispy because of the method of cooking it. It is twice-fried, which gives it a crispy texture on the outside while keeping the meat inside tender.
The first fry cooks the chicken through and the second fry gives it a crispy texture. Additionally, it is often coated in a spicy or sweet sauce that adds flavour and helps to create a crispy crust.
The combination of the double frying and flavorful coating creates a unique and delicious taste.
