Entered for safe-keeping for ZWT. From "Jewish Cooking In America with Joan Nathan" by Maryland Public Television. Per one source, a pasilla chile is fresh, and called a chile negro if dried. In California, poblano chiles are also called pasilla chiles, if in error, but may be used in a pinch, and ancho chile peppers are dried poblano peppers. Use gloves when handling chiles, or you will be sorry. Serve with saffron rice, mashed potatoes, or couscous.
