On the meat side (not the fatty skin side), add some bourbon (or substitution) and rub it in. Placing the meat side down, wrap it in tin foil, and cook in the air fryer at 250°F (bake mode) for 40 minutes. Then pull out and poke holes in the skin; use a kebab skewer or even a toothpick

Place back into the air fry and cook for another 20 minutes. Once the timer goes off, pull out, sprinkle some kosher salt and baking soda on top, and rub them into the skin. This will help with the crispiness of the skin

Turn the Air Fryer to the air fry setting and turn it up to 400°F. Place the pork belly back in (if you have a lot of fat, you can drain off some, but don't throw it out, save for cooking later and be careful. It's really🔥) and cook for another 30 minutes or until crisped up

Sauce:

Bring an orange marmalade and some bourbon (or whatever you used as the above substitute) to a simmer. Serve underneath the pork belly
