Kulen is stuffed into the pig's caecum, which gives it its fat, pear-like shape; it is cold-smoked for weeks and then dried for many months.
Coarsely minced pork is mixed with generous amounts of paprika and garlic, stuffed into a wide casing, smoked slowly, then air-cured for months until dark and firm. It's sliced thick and sold at Slavonian markets and farm stands as the region's prized charcuterie.
