Not knowing this dish at all, I googled and found some that appear to follow the traditional ingredients of pig's head parts (ear, jowl, etc) along with pork belly and seasonings. IF someone here isn't familiar with the dish and can provide a TNT recipe, I'd start with that.
If DH needs it to be authentic, does he have a source to ask for a recipe?
