Pepperoncini are a variety of the species Capsicum annuum, like bell peppers an chilli peppers. They are also known as Tuscan peppers or banana peppers, sweet Italian peppers, and golden Greek peppers. While called "pepperoncini" in American English, in Italy these and other sweet varieties of peppers are known as peperoni (singular peperone), while the term peperoncini (singular peperoncino) is used for hotter varieties of chili peppers. The Greek varieties are sweeter and less bitter than the Italian varieties grown in Tuscany. Pepperoncini are mild with a slight heat to them, and are commonly pickled and sold packaged in jars.
