Cut the pork chop into 1" pieces. Combine the remaining ingredients into a marinade, then marinate the pork in the fridge. Longer is better, ideally go at least 30 minutes, but overnight is best.
Place the pork into the air fryer basket with at least 1/4" gap between pieces, in a single layer. Set the air fryer to 375ºF for 8 minutes (see note).
Enjoy with white rice or on its own as a snack.
Notes
Note: If you prefer your pork on the more well done side, set it to 10 minutes instead.Feel free to save the marinade in the fridge to use again within 24 hours, or bring to a boil for 1-2 minutes to use as a sauce or glaze for an extra rich char siu.
