'Nduja (pronounced [nˈduːja]) is a particularly spicy, spreadable pork salumi from Italy. It is very similar to sobrassada from the island of Mallorca in Spain. 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 salumi,^[1] loosely based on the French andouille introduced in the 13th century by the Angevins.

'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.^[2] 'Nduja originates from the small southern Calabrian town of Spilinga^[3] 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.^[4] For example, it can be added to pasta sauces.

'Nduja's popularity boomed around 2015–2016 in the US and the UK, and it was featured in dishes at restaurants including New York City's Spotted Pig and London's Temple and Sons.^[5][6][7][8]
