This dish is the epitome of Czech and Slovak cooking. Because of the marination process, it needs to be started preferably three days before serving the meal.
Cut slits into the joint and push the strips of bacon inside. Put the onion in a pan with the carrots, parsnip and celeriac and add 1.5 litres/2½ pints/6¼ cups water. Bring to the boil, add salt, vinegar, bay leaf, peppercorns and allspice, and cook for 5 minutes. Cool.
Put the meat into a large bowl, add the vegetables and stock so to cover most of the meat. L
