Kung pao chicken

2 boneless skinless chicken breasts, or about 2/3 lb, cut into about 1/2 inch cubes
3 cloves garlic, sliced
about the same amount of ginger, also sliced
5 scallions, white parts only, chopped
peanut oil
at least 10 dried chilies, cut in half and seeds discarded
1 tsp whole Sichuan pepper
2/3 cup roasted unsalted peanuts

Marinade:
1/2 tsp salt
2 tsp soy sauce
1 tsp Shaoxing rice wine or medium-dry sherry
1 1/2 tsp potato flour or 2 tsp cornstarch
1 tbsp water

Sauce:
3 tsp sugar
1 tsp potato flour or cornstarch
1 tsp dark soy sauce
1 tsp light soy sauce
3 tsp Chinkiang vinegar
1 tsp sesame oil
1 tbsp chicken stock or water

Marinate the chicken. Make the sauce.
Heat oil in the wok. Add chilies and Sichuan pepper, stir fry until crisp, spicy, fragrant - careful not to burn.
Add chicken and fry on high, stirring constantly. As soon as it's separated, add the ginger, garlic, scallions, and for a few minutes.
Add the sauce, then the peanuts, then serve.
