Lava Rock Charbroilers
Lava rock charbroilers use the lava rocks (also know as char rocks) that are heated by the flame and in turn heat the char broiler's grate. These char rocks provide you with a considerable amount of BTU heat energy. Char rocks and lava rocks are in many ways similar to the type of coals used in outdoor BBQ cooking and like BBQ coals, will need to be replaced periodically. Chef's will often push the rocks around inside the charbroiler to move the heat into specific locations allowing them to achieve different finishes on the food.
