Saveraet for chickens. Take young chickens and cut them up completely into small pieces, which you will stew in a pan with fresh pork fat. Then take some onions and stew them therewith then take the livers of the chickens and mix them with meat broth. Add also some breadcrumbs to bind it, but you must pass it through a sieve. Add thereto also white ginger and verjuice then salt it just enough.
