The chiltepin pepper, hailed as the 'mother of all chilis', holds a special place in Tucson's culinary identity. This tiny, fiery pepper is native to the Sonoran Desert and is considered to be the oldest form of chili, significantly pre-dating domesticated varieties such as sweet bell peppers, jalapeños, and cayenne peppers. Small and round, with a striking red color, the chiltepin delivers a short but intense kick of heat, and is known for its complex flavor profile, adding citrus notes and a punchy smokiness to many of Tucson's best-known Mexican dishes.
