Charcoal-Grilled Flank Steak

Ignite about 7 quarts charcoal and burn until coals are completely covered with thin coating of light-gray ash, 20 to 30 minutes. Pile coals on one-half of grill bottom, position grill rack and heat until very hot (you can hold your hand 5 inches above grill surface for 2 seconds).

Generously sprinkle both sides of steak with salt and pepper; place directly over coals and grill until well-seared and dark brown on first side, 5 to 7 minutes. Flip steak using tongs; continue grilling on second side until interior of meat is slightly less done than you want it to be when you eat it, 2 to 5 minutes more for medium-rare (depending on heat of fire and thickness of steak). Transfer meat to cutting board; cover loosely with foil, and let rest 5 to 10 minutes. Slice very thin, on bias against the grain; adjust seasoning with additional salt and pepper and serve immediately.
