Ingredients 
1 litre of stock 
130g slow cook polenta 
25g butter 
Salt 

Method 
Put the stock into a large saucepan and bring to the boil.  Reduce the heat to medium, take a whisk and start whisking the stock.  Slowly but steadily sprinkle your polenta into the stock, whisking the whole time.  Once all of the polenta has been added you don’t have to stir constantly but will need to stir often to stop it sticking and going lumpy. 

The polenta will take 30-40 minutes to cook and when it is, it should be soft and thick and the grains won't feel like individual granules but smooth and unctuous.  Take your butter and stir it through then check the seasoning.
