Using the pestle and mortar, pound the garlic, pepper, lemongrass, coriander and salt. Set aside once done.
Sear off the pork belly in a medium heat pan. This will ensure the pieces hold together nicely even after they have been braised. When they start to brown remove from the pan and set aside.
In the same pan, with the remaining oil from the pork, add the ingredients we just pounded. Fry for about 1 minute to release the aromas. Then add Shaoxing rice wine to deglace the pan.
After most of the alcohol had evaporated, add back the pork belly pieces and the rest of the seasoning. Then add the water.
Bring it back to boil, then turn down the heat to a simmer. Cook on low heat for 3 hours. The pork belly pieces will be soft and tender but should still hold together very well.
