Roast the pork for 1¼ hours, adding extra stock if needed. Increase the temperature to 200°C (fan assisted) and roast for another 15–20 minutes to ensure the crackling is crispy and the pork is cooked. To check if the pork is cooked, insert a skewer into the thickest part of the meat. The juices will run clear when cooked. Remove the pork from the roasting dish, keep warm and set aside to rest.
