- 2tbsp vegetable oil
- 1.25kg (2lb 12oz) leg of pork, with the bone in
- 1 medium swede, trimmed and cut into 1cm (½in) cubes
- 25g (1oz) fresh root ginger, peeled and finely chopped
- 1 onion, finely chopped
- 1 garlic clove, chopped
- 100ml (4fl oz) cider vinegar
- 3 heaped tsp English mustard powder
- 100ml (4fl oz) pork or vegetable stock
- 400g can cannellini beans
- 2tbsp tarragon, roughly chopped
Preheat the oven to 180 C, 160 C (fan oven), 350 F, gas 4. In a frying pan, heat 1tbsp of the oil, add the pork, and season. Brown for 10 minutes on each side.
Meanwhile, heat the remaining oil in a casserole and fry the swede, ginger, onion and garlic for 5 minutes. Remove from the heat and stir in the cider vinegar, mustard and stock.
Add the pork to the casserole and bring to the boil. Cover and cook for 1½ hours or until the meat falls off the bone.
Rinse the cannellini beans under cold, running water, then spoon around the meat. Stir in the tarragon. Return the pot roast to the oven and cook, uncovered, for 30 minutes.
Taste the stock and season again, if necessary. Separate the meat from the bone and carefully spoon the pork and juices into a deep bowl and serve.
Chef’s secrets 1) English mustard powder works best here, rather than made mustard – it will be far more pungent. 2) Many pork producers now offer mail order, and whatever you do, buy British. The British Meat Quality Standard Mark guarantees that the pork has been produced to the highest standards of food safety and animal welfare. 3) You could use a hand of pork or a cut from the shoulder instead of the leg, but these tend to be more fatty.
