In a bowl, combine hoisin, honey, soy sauce, Shaoxing wine, brown sugar, five-spice powder, minced garlic, white pepper, and red food coloring (if using). Whisk until well combined to create the marinade.

Cut the pork into long strips, about 1.5-2 inches thick, then place them in the bowl with the marinade, ensuring they are fully coated. Cover and refrigerate for at least 4 hours or preferably overnight, turning occasionally; reserve about 1 tablespoon of the marinade for basting.

Preheat your air fryer to 375°F (190°C) for 5 minutes.

Place the marinated pork strips in a single layer in the air fryer basket, ensuring not to overcrowd, and cook for 10-12 minutes before flipping.

In a small bowl, mix the reserved marinade with 1 tablespoon of honey, then brush this glaze onto the pork and continue to air fry for another 8-10 minutes, flipping once and basting again until caramelized and cooked through.

Remove the char siu from the air fryer and let it rest for 5-10 minutes before slicing, then serve warm with rice or noodles.
