Try the Firenza Jalapeno from Shepherd's Seeds. It is available in the 5-pepper pack and it really is a hot jalapeno. It has great heat and flavor. We grow them every year. They are excellent in salsas. The url for Shepherd's Seeds is now www.whiteflowerfarm.com. Look for the Chile Pepper Collection. I don't think you can purchase the Firenza seeds just by themselves, but everything in the pepper collection is good. Enjoy! Dot in DEE-troit
