Black Pepper Chicken With Celery

Soak one dried chili with 2 tablespoons of white vinegar for an hour.
Marinate chicken pieces with soy sauce, cornstarch, chicken bouillon powder, half of the chili vinegar, baking soda, garlic powder, sliced ginger
Heat oil on high heat, stir fry a few pieces of chicken skin to render the fat. Discard chicken skin. Add chicken to pan and stir fry until cooked
Set chicken aside. In the same pan stir fry thinly sliced celery hearts (only the pale green parts) and sliced onions for about 30 seconds. Add some cooking wine to deglaze.
Add chicken back to the pan. Add soy sauce, rest of the chili vinegar and freshly ground black pepper. I use a spice grinder to grind 1 tablespoon of black peppercorns.
Mix well and serve immediately with steamed rice.
