I made an experimental char siu with pork belly. Cooked in the air fryer. (Note, if you try this, put it directly under your exhaust vent as it will make copious quantities of smoke. I think pork belly is just too fatty for the air fryer. Next time I will probably cook in the pellet grill.) Made into a very non-traditional stir fry of arugula, carrot, onion, celery and cauliflower. It was very tasty though!
