Tomatillos can be used raw or prepared in one of many ways – roasting, boiling, simmering. That way I like to do them is roasting them over fire – especially if you have an open fire-pit outdoors. You can make makeshift an open fire-pit indoors with a grate placed over gas stove burner, then give some color to your tomatillos. This recipe specifically uses oven-roasted tomatillos for ease of preparation. Use fresh or store refrigerated for one week.
