Nduja is a spreadable salami originating from the Calabria region in southern Italy. It is made from pork, particularly the fatty parts, and is seasoned with spices, including red pepper, which gives it a distinctive spicy flavor. The mixture is then cured and aged, resulting in a soft, spreadable texture that is often enjoyed on bread or as a pizza topping. This unique sausage has gained popularity beyond Italy, finding its way into various cuisines around the world. Chefs appreciate its versatility, using it in pasta dishes, sauces, and even as a flavor enhancer in soups and stews.
