Bird's eye chili in the context of "Asian cuisine"

Chili peppers, also spelled chile or chilli (from Classical Nahuatl chīlli [ˈt͡ʃiːlːi] ), are varieties of berry-fruit plants from the genus Capsicum, which are members of the nightshade family Solanaceae, cultivated for their pungency (spicy heat). They are used as a spice to add pungency in many cuisines. Capsaicin and the related capsaicinoids give chili peppers their intensity when ingested or applied topically. Chili peppers exhibit a range of heat and flavors. This diversity is the reason behind the availability of different types of chili powder, each offering its own taste and heat level.

Chili peppers originated in Central or South America and were first cultivated in Mexico. European explorers brought chili peppers back to the Old World in the late 16th century as part of the Columbian Exchange, which led to the cultivation of multiple varieties across the world for food and traditional medicine. Five Capsicum species have been widely cultivated: annuum, baccatum, chinense, frutescens, and pubescens.

This is a list of Capsicum cultivars belonging to the five major species of cultivated peppers (genus Capsicum): C. annuum, C. chinense, C. baccatum, C. frutescens, and C. pubescens. Due to the large and changing number of cultivars, and the variation of cultivar namings in different regions, this list only gives a few examples of the estimated 5000 pepper varieties that exist.
