• Remove the membrane from the back of the ribs by sliding the knife underneath and slowly pulling it off. Use a paper towel to get a good grip and slowly pull the membrane off.
• Rub the ribs with the gochujang, covering all sides.
• Pour the sake and ½ cup of water in the bottom of the Instant Pot. Place the ribs in the Instant Pot on high pressure for 27 minutes. 
• When the ribs are done, let the pressure release naturally for 10 minutes. Then use the quick release to release any remaining pressure.
• Place your ribs on a parchment paper (or foil) lined baking sheet and brush the sauce on both sides.
• Place the ribs under the broiler for about 5-10 minutes, until it starts to sizzle and caramelize. Watch them carefully as they can burn quickly. 
• Slice, garnish with sesame seeds and green onions, and serve.
