jalapeño pepper

The jalapeño (Capsicum annuum var. annuum) is a medium-sized chili pepper native to Mexico, characterized by a smooth, waxy green or red skin and a conical shape typically 5-9 cm in length. Named after the city of Xalapa in Veracruz, Mexico, jalapeños belong to the Capsicum genus and are moderately hot peppers, ranking 2,500-8,000 on the Scoville scale. The pepper's heat derives from capsaicin, an alkaloid compound concentrated in the seeds and white membrane.

Jalapeños possess a bright, vegetal flavor with subtle fruity notes and grassy undertones. When fresh and young, they are firmer and milder; as they mature and turn red, they develop greater heat and sweetness. The heat level varies depending on growing conditions, with stress (such as drought) increasing capsaicin production. Dried and smoked jalapeños are known as chipotles, which develop a deep, smoky character with complex heat.

Jalapeños are fundamental to Mexican cuisine and widely used in global cooking as a versatile chili pepper. Fresh jalapeños appear raw in salsas, guacamole, and pico de gallo, or are sliced into rings for nachos and tacos. They are also stuffed with cheese to make chiles rellenos, pickled for condiments, or incorporated into cornbread and other baked goods. In contemporary cuisine, jalapeños are grilled, roasted, or breaded and fried. They complement both seafood and meat preparations, and work well with acidic ingredients like lime and vinegar. The pepper's moderate heat makes it accessible to broader audiences while still providing significant flavor impact.
