Combine all the marinade ingredients in a bowl and mix well.
Add the pork strips and turn each piece in the marinade to ensure they're well coated.
Allow the pork to marinate at least overnight, 2-3 days is preferred for full flavor.
Place the pork strips on an air fryer rack. Air fry at 400°F for about 6 minutes or until the pork develops charred bits. Flip the meat over and char the other side. This will take another 6 minutes.
Make the glaze by mixing together honey and water.
Baste the pork strips with glaze on all sides. Turn the heat down to 300° F and air fry for another 20-30 minutes. Halfway through cooking flip the pork and brush on another coat of glaze.
Use an instant read thermometer and check the internal temperature of the thickest part. The Char Siu is ready when it reaches an internal temperature of 145°F. The timing will vary depending on the thickness of your pork.
Remove the Char Siu from your air fryer, cover it with foil and allow it to rest for 10 minutes before slicing.
