Prepare the meat by making 2 inches long cuts on the pork belly (the meat side) and deep enough to let the marinade penetrate evenly on the meat.
Make some deep cuts also on the skin side of the meat and rub a generous amount of salt on both sides.
Smoke the meat for about two hours. (search smoking procedure in this blog)
To make the marinade, in a large bowl or container, mix all the ingredients, condiments and spices except the pork, and stir until the sugar dissolved and the marinade is well mixed.
Then get a container that can accommodate the large chunk of pork belly.
Get the smoked pork belly and place inside the container and pour the marinade.
Place the container with the pork and marinade in the fridge overnight.
In a large wok or pot put the meat and the marinade and simmer for at least 3 hours or until tender.
Let the liquid evaporate until the mixture is reduced to half and add water if necessary.
Pierce a fork to know if the meat is already cooked. Serve the pork in half inch slices.
