'Nduja is made using meat from the head (minus the jowls, which are used for guanciale), trimmings from various meat cuts, some clean skin, fatback, and roasted Calabrian chilli peppers, which give 'nduja its characteristic fiery taste. These are all minced together, then stuffed in large sausage casings and smoked, creating a soft large sausage, from where the spicy mixture later is scooped out as needed. 'Nduja is mainly served with slices of bread or with ripe cheese. Its unique taste makes it suitable for a variety of dishes. For example, it can be added to pasta sauces. It is sold in jars or as thick slices from the soft 'nduja sausage. In past 'nduja was a mix of remnants of meat, eaten by poor people in Southern Italy.
