For the Sauce: Combine honey, vinegar, wine, soy sauce, and cornstarch in a small bowl. Stir together with a fork until no clumps of cornstarch remain. To Stir-Fry: Pour a small amount of oil into the bottom of a large wok or skillet and rub around with a paper towel. Place over high heat and preheat until smoking. Add remaining oil and immediately add chiles and Sichuan peppercorns. Stir-fry until fragrant but not burnt, about 5 seconds. Immediately add chicken and stir-fry until there are no longer pink spots on the exterior (chicken will still be raw in center at this stage), 45 seconds to 1 1/2 minutes.
