'Nduja, pronounced 'nduia in Italian or 'ndueea in English, is a soft, spreadable Calabrian salami made with a tremendous amount of red pepper, which gives it a threateningly reddish cast and a very refreshing burst of heat. Though one can spread it as is over bread (or add it to sauces or whatnot), the nicest way to enjoy it is to scoop it out of the casing with a spoon, warm it in a little pot over a candle flame (Calabresi use terracotta warming pots), and dip bread into it. It's a fantastic antipasto or party food.
