My Instant Pot never lets me down and this recipe is FOR SURE proving that! I am obsessed and will be making ribs constantly. My dad even said there is no need for all those lengthy tedious steps.
First you are going to find the membrane by flipping your ribs over so that they are curving toward you. Bone side facing you. You will see a thin translucent type of tissue attached.
Then once you have pulled up the part of the membrane you should be able to continue to pull it up using your fingers until it has fully operated from the ribs along the whole rack.
