The cascabel chili (little bell), also known as the rattle chili, is one of the Mirasol cultivars of the species Capsicum annuum. The 'rattle' and 'bell' designations describe the tendency of loose seeds to rattle inside a dried cascabel when shaken. The pigmentation of the fresh chilis blends from green to red; when dried, the color darkens.
The chile is moderately hot (it is a 4 on a scale of 1 to 10) and have a nutty flavor with a rich tannic and slightly smoky nuance but not an excessive amount of heat.
