1, first soak the wings in water for one hour, and then soak them in bloodletting water.

2. Put Korean sweet and spicy sauce, mashed garlic, oyster sauce, honey and soy sauce into a bowl, add some boiling water and stir well.

3. Drain the soaked chicken wings and marinate them in the mixed sauce for 4 hours (I marinated them the next night, which is more delicious).

4. Put the marinated chicken wings in a baking tray and sprinkle with a little black pepper, 180 degree baking 15 minutes.
