actually have got two pork belly pieces and am doing one in jerk paste and the other in Thai paste (made from fish sauce, lime juice, kaffir lime, lemon grass, shallots, garlic, coriander leaf, ground coriander, sweet soy sauce (you could use regular soy sauce + palm sugar), chinese wine, spring onions).
