Preheat oven to 300 degrees F. Line a baking sheet with parchment paper.
Sprinkle both sides of the ribs with salt and pepper. Lay them in a single layer on the parchment paper.
Bake for 2.5-3 hours until the ribs are juicy and tender.
While the ribs are baking, prepare the sauce. Place the rest of the ingredients, except chopped green onions and sesame seeds, in a food processor until thick and smooth. Set aside.
Once the ribs are done, pour out the oil that's been cooked off and discard the parchment paper.
Separate the ribs into sections using kitchen shears or a knife. Lay them out on the baking sheet.
Slather on 1/2 of the sauce on top of the ribs.
Broil for 3 minutes.
Remove from oven, flip the ribs, and slather on the rest of the sauce on the other side of the ribs.
Broil for 2-3 minutes until the sauce is thick and caramelized.
Sprinkle with chopped green onions and sesame seeds before serving
