Instructions
In a bowl, combine the chicken thighs with light soy sauce (for marinade), Shaoxing wine (for marinade), cornstarch (for marinade), and kosher salt; toss well and let stand 15 minutes.
In a separate bowl, whisk together the sugar, black vinegar (Chinkiang), light soy sauce (for sauce), dark soy sauce, water, and cornstarch (for sauce) until smooth; set aside.
Heat a wok over high heat until lightly smoking. Add the peanut oil, then the Sichuan peppercorns and dried red chiles; stir-fry until fragrant and the chiles deepen slightly in color, 30β45 seconds (do not burn).
Add the marinated meat and stir-fry over high heat until nearly cooked through and lightly browned at the edges, 3β4 minutes.
Add the ginger and garlic, then the whites from the scallions (cut into 1-inch pieces); stir-fry until aromatic, 30β60 seconds.
Stir the sauce to recombine and pour it into the wok; cook, tossing constantly, until it thickens and glazes the meat, 1β2 minutes, and the meat is just cooked through.
Fold in the roasted peanuts and the reserved greens; toss 20β30 seconds. Serve immediately with steamed rice if desired.
