'Nduja is a traditional spicy, spreadable pork sausage from Calabria, believed to originate in a small town of Spilinga. Known for its fiery flavor, creamy texture, and versatility in cooking, 'nduja originated in rural Calabria as a way for farmers to utilize less desirable cuts of pork by mixing them with a high concentration of chili peppers for preservation and flavor.

It is typically made from pork fat, meat (especially shoulder or belly), and an abundance of Calabrian chili peppers, which give it its distinctive red color and intense spiciness. The high fat content results in a soft, spreadable texture, setting it apart from traditional cured sausages.

After the ingredients are mixed, 'nduja is stuffed into natural casings and cured for weeks or months, allowing the flavors to develop while maintaining its creamy, paste-like consistency. Its bold, smoky, spicy, and slightly tangy flavor makes it a unique ingredient in Italian cuisine. 'Nduja is incredibly versatile; it can be spread on crusty bread as an appetizer, melted into pasta sauces, used as a pizza topping, or incorporated into soups and stews for a spicy kick.
