Preheat the oven to 170°C/150°C fan/350°F.
In a measuring jug, add 80ml extra virgin olive oil, the garlic, preserved lemon, oregano, dijon and lots of salt and pepper. Mix well.
Halve the baby potatoes and add to the base of a Dutch oven with a lid or a large roasting tin. Then lay the Half Leg of Lamb on top. Score the fat with a sharp knife, then pour over the marinade. Massage in.
Add the chicken stock and white wine to the dish, pouring over the potatoes and avoiding the lamb.
Tear a large sheet of parchment paper, scrunch it up and then cover the lamb. Cover with a lid (if you don't have a lid, cover tightly with foil).
Roast in the oven for 4 hours. At the 2 hour mark, flip the lamb.
After 4 hours, if it isn’t meltingly soft when you poke it, give it another 30 mins.
Once meltingly soft, remove the lid and parchment. Turn the oven up to 240°C/220°C fan/460°F. Flip the lamb once more, and baste with the juices.
Place back in the oven for 20 minutes so the lamb turns golden brown and the potatoes gain some colour.
Once the lamb is soft, pull it apart around the bone, then baste with the pan juices. Garnish with pomegranate seeds and fresh mint.
