Cascabel chiles are small, plump, round, and smooth chiles that ripen from green to red. When dried the color darkens to a deep reddish-brown with an almost transparent but thick skin. When mature they are about 1-1/2” in diameter. Unlike many chiles these are known by the same name whether fresh or dried. Recipes that call for Cascabel chiles typically are referring to the dried chile.
This chile is considered a mild heat chile (1,000-2,500 on the Scoville Heat Scale) and has a roasted, nutty taste.
