Mulato chiles are dried Poblanos. The name Poblanos pays homage to the native region these chiles were first cultivated which is a city in Mexico called Pueblo. Poblano translates to “pepper from Pueblo”. Dried Mulato chiles are part of the “holy trinity” of Mexican chiles (along with the dried Ancho Chile and the dried Pasilla Chile). Mulato chiles are from the plant species Capsicum annum. Mulato chilies are grown in central Mexico and these are a wide chile, about 2-3 inches wide and about 4 inches long. These dark brown chiles have a medium thick skin and are only sold dried.
