Roasted Tomatillo-Poblano Salsa
This chile pepper is often mislabeled ‘Pasilla’, which is a different pepper entirely.It is one of the most popular chiles in Mexico and has won the appreciation of many a chef worldwide because of the superior flavor it has over regular bell peppers.
They have a tough outer skin that usually requires roasting and peeling before use. These very large chile peppers are most popular in chiles rellenos recipes, but cooking with these as a substitute for bell peppers in any recipe will enhance the flavor.
