Our gas BBQ has a layer of Lava Rock above the gas burner. The rock gets hot which cooks the meats, thereby causing the juices to drip on to the hot rock, which then smokes off giving the smoked BBQ flavour to the meats.
Yes, In our garden we have a big gas Weber. They have what they call flavouriser Bars, these are a peaked roof shape pieces of steel over each line of flame, they take all the heat. They add that “cooked on a BBQ” flavour because drippings, marinades and juices from food being cooked fall down onto the red hot bars, and are vaporized and circulate back up to the food. As tasty as a charcoal? I can't tell the difference.
