A mild to medium-hot, rich-flavored chile that, when dried, is known as the pasilla. The narrow chilaca can measure up to 9 inches long and often has a twisted shape. It turns from dark green to dark brown when fully mature. About the only place it can be found fresh in the United States is in farmer's markets.
