Charred Tomatillo Guacamole

Preheat broiler.

Broil tomatillos in a flameproof shallow baking pan about 4 inches from heat until tops are charred, 7 to 10 minutes. Turn tomatillos over with tongs and broil until charred, about 5 minutes more.

Combine onion, chiles, cilantro, salt, and pepper in a large bowl. Add tomatillos 2 at a time, mashing with a fork or pestle to form a coarse paste.

Pit and peel avocados. Add avocados to mixture and continue mashing until incorporated but still chunky.
