In a tall pot, add water to boil. Water should be enough to submerge pork. Turn on heat to medium or medium high. Bring to a boil, while adding your salt, black pepper, onions, and bay leaf. Mix well.
While water comes to a boil, add your clean pork belly. You may cut the pork belly in half to fit in pot. Let boil until tender. Check occasionally for texture doneness. Add extra water if needed. You should be able to poke pork with a fork easily.
Remove pork belly and place on a baking sheet, lined with paper towel. The pork needs to be dried out and cooled before frying. Add an extra paper towel over top so both sides dry.
After, sprinkle more sea salt over all the pork. Don't be shy with the amount. After, place again on paper towel to dry more.
Prepare for frying: Place pot on medium heat. Add lard to a tall, but not large pot. A wok surprisingly works.
Add lard to pot and melt down completely.
Add all of your pork piece, THEN RUN! SEE NOTES PLEASE ****
Let fry for 5-10 ten minutes. Periodically, check if the meat starts to become golden brown, by flipping a few pieces. Turn pork oven to cook all sides evenly.
Removed golden-fried pork from pot/frying pan onto a paper towel lined baking sheet to remove excess oil.
Cool before consuming.
Enjoy!
