'Nduja

'Nduja (Calabrian: [nˈduːja]) is a spicy, spreadable pork sausage from the Calabria region of Italy.

It is sold in jars or as thick slices from the soft 'nduja sausage.

'Nduja was originally a mix of remnants of meat, eaten by poor people in southern Italy.

In the United States and the United Kingdom, 'nduja's popularity boomed around 2015–2016, and it was featured in dishes at restaurants including New York City's The Spotted Pig and London's Temple and Sons.

Another theory is that French andouilles had already been introduced in the region during Norman rule in Sicily and later evolved into 'nduja after chilis were introduced in Europe from America in the Columbian exchange.
