How Do You Place Lava Rocks In A Barbecue Grill?
Lava rocks are coarse, jagged pieces of igneous rock—molten magma that hardens as it cools—that are used in barbecue grills to absorb and reflect the heat given off gas burners quickly and evenly. They are reusable and long-lasting, but over time can become brittle and crumble. They also absorb grease and odors, which can affect food flavor, so it’s best to replace them every other year, depending on how often the grill is used. Here’s how to place lava rocks in a grill to give your barbecuing a boost. Remove all old lava rocks from the metal grate over the burner and sweep out debris from inside the grill when it is cool and shut off. Replace the metal grate over the burner and pour about 10 pounds of lava rocks onto the grate. Larger grills may require more lava rocks, so buy an extra 10-pound bag. Lava rocks are sold in hardware stores and grill specialty shops. For even cooking, arrange the lava rocks in a single layer so that each rock is touching the edge of surrounding rocks
