2. In the same pan, add another tablespoon of oil and soften the vegetables, melting them a little but not colouring them. Once done, layer the vegetables in the base of a baking dish and place the browned oxtail on top.
3. Return the vegetable frypan to the element, stir in the red wine and beef stock scraping up all the oxtail and vegetable residue from the base of the pan as you bring it to the boil.
4. Add the tinned tomatoes and stir together. Pour over the oxtails and vegetables in the baking dish.
5. Cover the dish with tin foil and braise in the medium oven for one hour. Remove the foil, add the white beans. Return to the oven, uncovered, turn down the temperature to 160C. Cook for a further hour, so that the liquid reduces and thickens to a saucy consistancy.
Check for seasoning, scatter with chopped parsley and serve with a good crusty bread to mop up the juices.
