With the flip of a switch, you can heat a gas grill without having to attend to it. Gas is used to heat semipermanent ceramic briquettes or lava rock, which are made from natural volcanic stone. These line the grate and radiate heat to cook the food.
How to Buy
Gas grills come in all shapes, sizes and price ranges, from tabletop models to elaborate wagons complete with side burners, cutting boards and condiment trays. Most often fueled by refillable liquid propane (LP) gas tanks, other models can be fueled through a natural gas line. The larger the grill, the higher the BTUs, increasing cooking efficiency. Larger gas grills will have at least two burners.
