The mulato pepper (Capsicum annuum) is a mild to medium chili pepper, closely related to the poblano (ancho), and usually sold dried. Mexican mulato chiles are part of the famous “trinity” used in mole, as well as other Mexican sauces and stews. The mulato’s color while growing is dark green, maturing to red or brown. The dried mulato is flat and wrinkled, and always brownish-black in color. The average length and width of the mulato is 10 cm and 5 cm, respectively.
