Make a lengthwise cut to skin of the pork knuckle with sharp knife, otherwise, the skin may tighten in the oven and squeeze out the juices from the meat.
Take a large freezer bag and put the marinade ingredients in the bag. Stir to mix.
Put the pork knuckle in the bag and marinate for 24 hours in the fridge.
Start the oven on full heat.
Take out the pork legs from the fridge and place in the oven tray. Thickest skin side up.
Pour the marinades into the baking dish.
Place the pork legs in the oven. Turn the heat down to 150°C and cook for 2-3 hours. Keep spooning the marinade over the meat occasionally. You may add some water if it gets dry.
The pork legs are cooked when the meat comes off the bone easily.
Notes
Score the skin before cooking to prevent it from tightening and to help it crisp up.
Marinating for 12–24 hours improves flavour significantly.
Baste the meat with the cooking liquid during roasting to keep it moist.
Increase the oven temperature at the end for extra crispy skin.
