On the day before you cook it, pierce a few holes in your pork leg with a sharp knife. You want to let all those lovely marinade juices in!
In a tray large enough to hold the joint; mix the wine, lemon juice, cloves, bay leaves, onions, garlic, parsley , olive oil, the paprika, the salt and pepper. Place the joint in the middle and rub everything in thoroughly. Cover with cling film and place in the fridge for at least 12 hours, turning every now and again.
One hour before cooking remove the joint from the fridge and bring it back to room temperature. In the meanwhile pre heat your oven to 200°C/Gas6.
Move the pork into a roasting tray, preferably a clay one. Pour the marinade over the pork, scatter the smoked bacon and the butter over it, cover loosely with foil and place it in the oven. Reduce the heat to 180°C/Gas4.
Keep basting your pork with the marinade juices to keep it nice and moist. After 2,30 hours place the potatoes all around the leg. Carry on cooking until the meat is soft and coming off the bone, about another hour. Remove the foil, raise the oven temperature to about 250°C/Gas9 and crisp it up for about 45 minutes.
Once it's done remove the tray from the oven and let the meat rest for 10 minutes before carving. Prepare your mixed salad and slice the oranges.
Slice the pork and serve with a couple of potatoes, salad and sliced oranges.
