Peel the turnip, carrots, and onion. Cut the carrots and onion in half lengthways. Cut the turnip into pieces that are roughly the same size as the carrots.
In a large pot place the meat with the carrots, turnip, onion and celery and cover over by 15 cm with cold water and add ½ tablespoon of salt.
Bring the pot to a boil then turn down to a medium simmer, skim of any scum that rises to the surface and cook for 2 ½ hours, until the meat and vegetables are tender. Remove from the heat cool and chill in the fridge for 24 hours. This will allow the soup to develop more flavour and is worthwhile doing.
