Heat 5/10. The famous Mexican pepper used to make chili powder. Fresh, they're "Poblano" peppers and are the one most often used to make Chilis Rellenos, battered fried stuffed chilis; a less than common and fairly complicated to make dish, but once you've tried you can't want for the next one. Dried, the chilli turns red and is called "Ancho" and is a staple of Mexican cuisine; it is what chilli powder is primarily made from.
