Cotechino is a kind of pure pork sausage made of skilfully dosed and minced meat, lard, bacon rind and the prestigious Barolo wine. It has to be cooked before eating and is best served very hot and in thick slices. It’s a classical Piedmontese hors d’oeuvre but can also be served as a delicious and tasty part to a main course.
