Dry the pork belly skin with kitchen paper. Mix the thyme
sea salt and black pepper together in a bowl. Rub this mixture all of the pork and skin
then turn the belly over and rub it on the underside of the pork.
Place the pork in a flameproof baking tray and roast for 25-30 minutes
or until the skin is crisp. Reduce the oven to 180C/160C (fan)/Gas 4 and roast for a further hour.
Mix the apples with the onions
sage and a little freshly ground black pepper and arrange in the middle of a small roasting tin.
Remove the pork from the oven and place it on top of the apples and onions
keeping the apple and onion pieces underneath the meat so they don’t burn. Keep the first roasting tin to one side. Return the pork to the oven and cook for a further hour
or until the meat is really tender.
Skim any fat from the cooking juices in the reserved roasting tin and place the tin over a medium heat. Stir in the flour and cook for a minute or so
stirring constantly. Gradually stir in the cider and l00ml/3½fl oz water and bring to a simmer. Cook for 3-4 minutes
stirring constantly. Strain through a sieve into a small saucepan and season to taste. Set aside.
Transfer the pork to a carving board. Spoon the apple and onion into a warmed serving bowl. Reheat the cider gravy until bubbling and cut the pork into thick slices. Serve the pork and crackling with the apple and sage and the hot gravy.
