Pat the rib steak dry, and allow it to air dry.
Place charcoal in a grill, and heat until it turns white hot. Season the steak liberally with salt and pepper. Sear directly on the hot coals for 30-45 seconds on each side, or until deeply caramelized and slightly charred.
Transfer the steak to a cooler part of the grill and finish cooking until it reaches medium-rare. Turn frequently to ensure gentle, even cooking. Allow the meat to rest for 3-4 minutes, then sprinkle with salt.
