Native to Mexico Pasilla Chiles are also known as chile negro or Pasilla negro and are actually the dried version of the Chilaca Chiles which are dark green chilies that pack a similar heat to the Poblanos pepper. These long, thin chile peppers are typically 5 inch- 6 inch in length and 1 inch wide at the top (by the stem). When dried the resulting Pasilla Chiles are almost black in color and their appearance is similar to that of a raisin. The taste is pungent but with a rich flavor and herb like undertones that is sophisticated and long-lasting. The Dried Pasilla Chile is a key chile in the famous "holy trinity" of Mexican chiles used in Mexican moles along with the Ancho and the Mulato chiles. Mulato chiles are closely related to the Ancho chile but they are not the same.
