Arista di maiale

1. Preheat the oven to 195°C. Mix the oil, rosemary, garlic and lemon zest.
2. Place the meat on a roasting rack that fits into a roasting tray. Using a sharp knife, make small incisions all over the meat. Rub the olive oil mixture all over the making sure it penetrates the incisions. Pour over the verjuice and roast for 3 hours.
3. Increase the oven’s temperature to 220°C and roast for a further 5 minutes.
4. Remove from the oven and rest for 15 minutes. Slice and serve.
Cook's note: Serve the pork with roast potatoes that can be added to the pan juices 1½ hours into the cooking time. You could also add a bunch of grapes halfway through. Swap the verjuice for white wine if you like.
