Mulato chiles, which are similar to ancho chiles, are a variety of dried poblano chile. They tend to have a darker color than ancho chiles and a fuller, slightly bitter taste.
To handle mulato chiles:
Wear kitchen gloves to prevent any cuts or abrasions on your hands from contacting the volatile oils. Wash your hands well with warm, soapy water after handling the chiles, and do not touch your eyes or other sensitive areas.For other varieties of chile, see Anaheim, ancho, árbol, bird's-eye, cayenne, chilaca, chipotle, guajillo, habañero, jalapeño, pasilla, poblano, serrano, and yellow chiles, and dried red chiles and ground dried chile.
