Char Anaheim chilies directly over gas flame on your barbecue or with your oven broiler until blackened on all sides. Enclose in paper bag; let stand 10 minutes. Rinse off all of the blackened skin and then chop the chilies.
Warning: Always wear gloves when working with hot chile peppers (fresh, dried or roasted chiles). Never touch your eyes when working with chiles.
