Ancho Chile Peppers

Anchos are the dried form of the Poblano, a mild to medium-hot chile shaped much like a bell pepper and about the same size.  In its dried form it keeps practically forever and is very handy for infusing dishes with a wonderful chile flavor.  You'll often find Anchos in the produce section of supermarkets where other dried products, such as sun-dried tomatoes, are found.  If you can't get Anchos you may substitute Anaheim or New Mexico chiles.
