Large (2 to 3 inches wide and 4 to 6 inches long), dark-green (almost black) chiles. Rich, earthy, mild to slightly hot. Often stuffed (as in Chiles Rellenos), roasted, and never eaten raw. Known as anchos when dried.
The Poblano is a mild chile pepper, just slightly spicier than a bell pepper . One of the most popular peppers grown in Mexico, the plant (of the "annuum" species) is multi-stemmed, and can reach 25 inches in height. The pod itself is about three to six inches long, and about two to three inches wide.
