Wash and dry the apricots and sultanas. Half the apricots.
Put them in a pan, add the butter and stock. Put the lid on and leave to cook on low heat. Important: do not fry. If you see that the stock is fully absorbed, add another spoonful of stock. Stew the dried fruit on low heat for approximately 30-45 minutes. The dried fruit will grow in size by absorbing not only the stock but also the butter. They will look like jade beads.
