1/2cup broth (chicken or beef)
1/4cup wine/sherry/(beer?)
a dash or two of liquid smoke
salt, pepper, and paprika
garlic cloves in broth
fat side up
1hr20min on high, pressure cook
That'll cook the pork belly, but you will still need to sear it (bake at a high temp or cast iron ... I cast iron, seems more economically efficient.
The sticky sauce I made, I just winged it, but it has beef broth, apple cider vinegar, brown sugar, wor. sauce, and cayenne - cooked down to a thick syrup.
After I seared the belly I tossed it in the sauce and let it sit to thicken up (not shown) and sprinkled some chunkier salt on top. That's pretty much it.
EDIT: I used to always sous vide my pork belly, but this method works very well (couldn't tell the difference) and much faster!! I've also smoked pork belly, and I would still go back to the InstaPot.
