Thaw the pork overnight. Wash with water and lime juice. Score the meat with a sharp knife. Cut through the fat, but too deep into the meat. You can also use an injector needle to inject the seasoning into the meat. Mix green season with salt, ginger and soy sauce. Rub the seasoning into the pork. Cover with foil and leave to marinate for 18 hours in the refrigerator.
Place the pork in a roasting pan to roast in the oven uncovered. Roast in a 350 degree F preheated oven for 30 minutes, then 325 degree F for 2 ½ hours. This gets the skin real crispy. Turn roast half way through roasting.
Mix the orange juice, salt, and olive oil in a separate mixing bowl. Every half an hour, brush the juice over the pork
