Harvesting: Harvest when mature size, and firm. Jalapeños can be harvested green or red, and are hottest just when they begin to turn from green to red. When harvesting, take care to avoid touching the interior of any broken peppers, as the capsaicin is an extreme irritant, especially to the eyes. Wash hands thoroughly after harvesting or wear gloves to harvest peppers.
