Bone out and skin the pork belly. Season both sides and roll belly tightly, tying with string. Sear in a hot frying pan until golden brown.
Chop carrot, chilli, leek, and onion and sauté with some oil in a large pot. Add apple juice and chicken stock, star anise and cinnamon.
Place pork into the liquid and cook in the oven for 2½ hours. Remove from liquor and leave to cool. Strain liquid from the braising stock and reduce by two thirds.
Once the pork is cool slice into desired portion sizes. Seal pork in a pan and then put back in braising liquor to heat through.
