01 - Whisk together hoisin sauce, honey, soy sauce, oyster sauce, Shaoxing wine, brown sugar, sesame oil, five-spice powder, ginger, garlic, and food coloring in a large bowl until smooth and fully combined.
02 - Add chicken thighs to the bowl, tossing thoroughly to coat all surfaces. Cover and refrigerate for at least 2 hours, preferably overnight for maximum flavor penetration.
03 - Preheat oven to 425°F. Line a baking sheet with aluminum foil and place a wire rack on top to allow air circulation and even cooking.
04 - Remove chicken from marinade, reserving the liquid for basting. Place chicken pieces on the wire rack with space between each piece for proper caramelization.
05 - Roast for 20 minutes to begin the cooking process and develop initial color.
06 - Brush chicken generously with reserved marinade, turn pieces over, and baste again. Roast for an additional 10-15 minutes, basting once more during this period, until edges are caramelized and internal temperature reaches 165°F.
07 - Let chicken rest for 5 minutes to redistribute juices. Slice against the grain and garnish with spring onions and sesame seeds. Serve immediately with steamed rice or noodles, or allow to cool for room temperature serving.
