Heat oven to 160C/140C fan/ gas 3. Heat the oil in a wide, shallow ovenproof dish (or use a roasting tin that can go on the hob). Mix the pomegranate juice, cinnamon, allspice, lemon juice, honey and red wine vinegar together in a large bowl. Brown the pork for 2-3 mins each side, then add all the other ingredients, season and bring to a simmer. Cover with a lid, or wrap the dish in foil, then transfer to the oven for 1 hr.
