Season the lamb with sea salt and freshly ground black pepper. Smash up the coriander seeds and fried chilli and mix with the chopped rosemary and fried marjoram. Roll the lamb in this mixture, pressing it in well. Dust the lamb with the flour.
Heat a thick-bottomed casserole pan, add the oil, brown the meat on all sides and then remove from the pan. Add the garlic, carrot, celery, onions and a pinch of salt and sweat them until softened. Add the balsamic vinegar and allow it to reduce to a syrup. Pour in the white wine and allow to simmer for 2 minutes.
Add the anchovies (these really seem to intensify the lamb flavour) and then add the tinned tomatoes, kept whole. Shake the pan and return the lamb to it. Bring to the boil, put on the lid and simmer in the oven at 180C/350F/gas 5 for 1 ½ hours, then remove the lid and cook for a further ½ hour. Skim off any fat and taste for seasoning.
Finally, stir in a handful of roughly chopped fresh basil, marjoram or flat-leaf parsley.
