The jalapeno is a fruit, a medium- to large-sized chili pepper with a warm, burning sensation when eaten. A ripe jalapeño is 2–3½ inches (5–9 cm) long and is commonly picked and sold when still green. It is a cultivar of the species Capsicum annuum originating in Mexico. It is named after Xalapa, Veracruz, where it was traditionally produced. 160 square km are dedicated for the cultivation in Mexico, primarily in the Papaloapan river basin in the north of the state of Veracruz and in the Delicias, Chihuahua area. Jalapeños are cultivated on smaller scales in Jalisco, Nayarit, Sonora, Sinaloa, and Chiapas.
