Barbecue is a cooking method that involves applying dry heat to the surface of food, usually from above or below. Barbecue typically involves a large amount of direct heat radiation and is often used for quick cooking of meat. Grills come in different shapes and sizes. In addition to tabletop grilles and rotating grills, cooking tripods are a popular over the fire cooking device. Tripods are superior to table grills due to their compactness and providing longer gaps (no more than 8.9 cm) for slow Dutch oven cooking on direct fire or fire pits.
