01 - Whisk together hoisin sauce, honey, soy sauce, oyster sauce, Shaoxing wine, brown sugar, five-spice powder, fermented bean curd, garlic, ginger, sesame oil, and white pepper in a large bowl until smooth and fully combined.
02 - Add chicken thighs to the bowl, turning to coat each piece thoroughly. Cover and refrigerate for at least 2 hours, preferably overnight for maximum flavor penetration.
03 - Preheat grill to medium-high heat. Alternatively, preheat oven to 425°F and line a baking tray with foil topped with a wire rack.
04 - Remove chicken from marinade, allowing excess liquid to drip off. Reserve the remaining marinade for basting during cooking.
05 - Grill chicken for 5 to 7 minutes per side, basting occasionally with reserved marinade, until caramelized and internal temperature reaches 165°F. For oven method, roast on wire rack for 20 to 25 minutes, turning and basting halfway through cooking.
06 - Mix honey with hot water to create basting glaze. Brush over chicken during the final 2 minutes of cooking to achieve sticky, glossy finish.
07 - Let chicken rest for 5 minutes to allow juices to redistribute. Slice against the grain and serve immediately with steamed jasmine rice and bok choy.
