Peperoncino (; plural peperoncini ) is the generic Italian name for hot chili peppers, specifically some regional cultivars of the species Capsicum annuum and C. frutescens (chili pepper and Tabasco pepper, respectively). The sweet pepper is called peperone (plural peperoni) in Italian. Like most peppers, the fruit is green or yellowish-green when young, and ripens to a red color. In the United States, peperoncini are usually pickled, comparatively mild – most often the variety known in Italy as friggitelli, a fairly sweet cultivar of C. annuum – and commonly used (whole, sliced, or chopped) as a condiment on sandwiches, in salads, and in Italian-style or other Mediterranean-inspired dishes. History The peperoncino probably came to Italy around the 15th century, when much of Italy was under Spanish dominion. It was likely an export from the new world among other plants new to Europe such as the tomato. Like the tomato, the peperoncino was first considered a decorative and possibly poisonous plant before it was adopted into Italian cuisine. It might have become popular as a food long before the cookbooks attest to its use. These cookbooks were written for the upper classes, while the peperoncino was a cheap and convenient food for the lower classes. Pietro Andrea Mattioli first described peperoncini in 1568 and mentioned how much hotter they were than other varieties of pepper from Asia. The earliest surviving published use of peperoncino in a recipe dates to a 1694 cookbook by the Italian chef Antonio Latini. In his recipe for , chopped peperoncini, tomatoes, and some onion are combined with peppermint, salt, and oil, to be served as a relish. Culinary use In Italian cuisine peperoncini are used with moderation and the flavour is considered more important than the heat. As a consequence the Scoville rating serves only as a rough guide to the heat, which is quite varied among the different cultivars. The peperoncino is especially important in Calabrian cuisine. In late summer, peperoncini are stitched on wires and hung from buildings. They are left to dry in spots with sunlight and ventilation to conserve them, allowing their use in cooking until the next harvest. They are eaten whole, fried until crisp, crushed, pickled, powdered or as a paste. A typical peperoncino from Calabria rates 15,000 to 30,000 on the Scoville scale. Notable Calabrian dishes which use peperoncini are the condiments , chili oil and the spreadable pork
