A ceramic grill like the Big Green Egg holds its temperature. These grills are ideal for large steaks like the long-bone ribeye. When you slowly bring the steak to temperature, you can easily achieve a perfect medium rare. Coals and wood chunks impart a smokey flavor. Reverse sear for edge-to-edge doneness. Although these instructions are specific to a ceramic grill, this technique can be done on a gas or conventional charcoal grill. Tip: Use a probe thermometer.
