' 'Nduja' is a particularly spicy, spreadable pork salume from Italy. It is typically made with parts of the pig such as the shoulder and belly, as well as tripe, roasted peppers and a mixture of spices. It is a Calabrian variation of salume, loosely based on the French andouille introduced in the 13th century by the Angevins.
The name derives from the Latin "inducere" (to lead in, bring in, introduce, conduct, lead up, bring forward). '' '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 hot red peppers which give '' 'nduja'' its characteristic fiery taste. 'Nduja originates from the southern part of Calabria, namely from the small town of Spilinga and its neighborhood. It 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.
