Marinate: In a large bowl, toss the pork shoulder strips with the Char Siu sauce, dark soy sauce, and five-spice powder until evenly coated.
Air Fry (Side A): Place the pork in the air fryer basket in a single layer, ensuring they aren't overcrowded so they get that "shatteringly crispy" texture. Cook at 330°F for 12 minutes.
The Flip: Open the basket and flip the pork strips over to ensure even caramelization on both sides.
Air Fry (Side B): Cook for another 13 minutes at 330°F until the edges are beautifully charred and the glaze is tacky.
Rest: Remove the pork from the air fryer and let it rest for at least one minute to allow the juices to redistribute.
Slice: Identify the grain of the meat and slice thinly across it for maximum tenderness.
