Essential Spice Dried Mulato Chilies are very similar to Ancho Chills.

As are Ancho Chilies, they are derived from poblano peppers, but have a distinct difference in flavor. These chilies produce a chocolate like- licorice flavor with a small hint of cherry, and can be seen in Mexican mole dishes, chilies, and in salsas. 

Mulato Chilies are often smaller in size than the more common Ancho Chili.
