Wash the pork belly, then place it in the pot with water, ensuring the pork is submerged in water. Add Lee Kum Kee Premium Oyster Sauce , bay leaves, onions, salt, sugar, pepper and bring to simmer. Cook for approximately 30 minutes or until the meat is tenderised. Once the meat is done, drain the water and let the meat cool and air dry for 2-3 hours, preferably under the sun. Score the skin of the pork belly without cutting into the inner layer of skin.
