1. Pre-cook the pork. Boil a pot of water and submerge the pork belly. Let it boil for 5 minutes and skim any excess scum off the water. Once done, take out the pork and place into an ice bath to stop the cooking.
2. Dry out the pork. Your goal here is to dry it out as much as possible. Remove the pork from the ice bath and wrap it with paper towels.Pat the pork until it's as dry as possible.If you have a meat tenderizer that can puncture holes into the meat, use it here. If you do not have one, feel free to use a fork. Make sure to puncture deep enough for the skin to leak out, but NOT deep to the point that it has a huge hole. These holes will help the fat escape to the skin, which will aid in the crisping process. The more holes, the better.
