Preheat the oven to 240 Degrees Celsius (fan assisted).
Score the skin of the pork in parallel lines about 2 cm apart.
Combine the salt, thyme and garlic and rub generously onto the whole leg - esp the skin.
Place pork onto a roasting rack and roast uncovered for 30 minutes. Then turn the oven temperature down to 180 Degrees Celsius and roast for a further 2 hours 30 minutes (or 25 minutes per 500 g in weight). At the thickest part, the thermometer should read 70 Degrees Celsius when done. Allow to rest for 30 minutes before carving.
Gently peel the potatoes and cut into halves or quarters. Place them in a large bowl or colander and give them a good shake (to rough up the surfaces of the potatoes).
Place the duck fat and oil in a large baking tray and pop into the 180 Degree Celsius oven for 20 minutes to heat up. Add the potatoes to the tray and roast for 1 hour (the last hour of roasting time with the pork), turning the spuds halfway through. When pork is removed after the last 1 hour, crank the heat up to 200 Degrees Celsius and roast the potatoes for a further 30 minutes (while pork is resting) until golden and crispy. Remove from the oil, place on paper towel to absorb excess oil and season generously with freshly ground salt and a few fresh thyme leaves.
While pork and spuds are in the oven, prepare the hanepoot apples.
Heat the butter in a large pan, add the apples and cloves and saute for a few minutes to give the apples some colour. Add the jerepigo wine, water and sugar and simmer uncovered for 15- 20 minutes or until apples are tender and liquid has reduced to one third.
During this time, prepare other veggies of your choice. Brussels sprouts, green beans, cabbage, carrots, peas...
For the cider gravy: Heat 15 ml butter in the roasting pan with its cooking juices and saute 1 thinly sliced onion with a few sprigs of fresh thyme until softened and caramelised. Add 500 ml apple cider or vegetable stock. Simmer until liquid is reduced by half. Make a paste with 10 ml corn flour and 30 ml water and whisk into the onion and cider liquid over moderate heat until thickened. Season with salt and pepper to taste. Tip, the more caramelised your onions are, the darker your gravy will be.
To serve: Pull crackling off the rested pork and break into pieces. Thinly slice the pork meat with a sharp knife and arrange on a serving platter or board with the crackling. Serve with crispy duck fat potatoes, hanepoot apples, onion and cider gravy and veggies of your choosing.
