In the same pan, sauté the onion and garlic until the onion becomes translucent. Put back the pork then add the vinegar and simmer for about 1-2 minutes (do not stir).
Add the peppercorn, dried bay leaves, soy sauce, pineapple juice or sprite and brown sugar. Stir and let it simmer for 15-20 minutes until the pork is tender.
Put the dried banana blossom and black beans, cook for another 5 minutes or until the sauce thickens. Serve immediately with hot rice!
