| Chipotle | Shared name (ambiguous) | Chipotle is smoke-dried ripe jalapeño, a process rather than a variety. Any red jalapeño cultivar can become one. |

Origin & history
The open-pollinated commercial jalapeño standard, and the line most seed sold as plain 'Jalapeño' descends from. Corky netting on the shoulders is normal at maturity and is a sign of ripeness rather than damage, though the fresh market treats it as a defect.
