Peperoncini (or pepperoncini) are a variety of the species Capsicum annuum. While called peperoncini in American English, peppers of this particular kind, in Italy, are called friggitello (plural friggitelli) or more generally peperone (plural peperoni) like other sweet varieties of peppers, while the term peperoncini (singular peperoncino) is used for hotter varieties of chili peppers.[1] The Greek varieties are sweeter and less bitter than the Italian varieties grown in Tuscany. Peperoncini are mild with a slight heat and a hint of bitterness, and are commonly pickled and sold packaged in jars.
