From the Science class, "The Flavor of Grilling" states that charcoal merely produce the aroma and taste of the grilled foods. The important is the drippings.
I would like to ask if the Lava rocks under the gas grill can achieve the similar result? I saw in Japan that they put stones inside the gas grill at the table and some izakaya put stones inside the gas grill when doing skewers.
Also are lava rocks and sauna rocks are the same? can they be use for grilling? are there any stones or rocks or any heat conduct material to use for grilling?
I am really curious and cannot find any article about this, Thank you for those who answer me
