Light approximately 100 charcoal briquettes in a chimney starter using balled newspaper as ignition. When briquettes are covered with gray ash (about 10-15 minutes), spread coals on one side of the grill to create two heat zones.

Remove steaks from the refrigerator and let rest at room temperature for about 20-30 minutes before grilling.
