Bean soup with knuckle of pork (bableves csulokkel)

500-600 g/1 lb smoked knuckle of pork
150 g/6 oz dried speckled beans
1 carrot (sliced)
1 parsley root (sliced)
1 small onion
1 clove of garlic
1 tablespoon of lard
1 tablespoon of flour
200 ml/ one third pint sour cream
paprika

1. Soak the pork with the beans for 24 hours beforehand, to remove some of the salt.
2. Cook the meat in fresh water with onion and garlic, for about 1 and half hours, until the skin is tender. Remove the onion and garlic and taste the stock to see if more salt should be added. If it is too saltry, throw away some of the liquid and dilute with more water.
3. Add the beans and other vegetables and simmer until they are cooked (about 1 and half hours more). If the soup is very greasy, let it cool down and skim the fat from the surface.
4. Prepare a roux from the lard and flour, stir in the paprika, then the sourcream. Pour into the soup and bring to the boil. To serve cut the meat into pieces, put a piece in each soup plate and pour the soup over.
