Transfer charred peppers to a paper or plastic bag, tie the top closed and let steam until cool to the touch, about 15 minutes.

To peel peppers, pull off the charred skin by hand and then, only if necessary, dip the peppers briefly in water to remove any blackened bits.

(Do not peel the peppers under running water since that would wash away the flavorful juices.)
