As I learn the art of making pizza, I rigged up my built in Lynx Gas Grill with a bunch of pizza stones, unglazed Mexican tile, and bricks. (Yeah, I know they aren't fire bricks, but they were cheap and this was for exprimental purposes).
The one thing this grill has that is beneficial for this experiment is a rotisserie burner on the backside of the grill. The back rotisserie burner sort of acts like a pile of burning coals and helps get the heat a bit higher.
With my infrared pyrometer I can get the bottom pizza stone about 750 degrees, and the top a little over 850.
This is my 4th pie ever. (No basil since the wife doesn't care for it). Just San Marzano tomatoes mixed with some garlic and sea salt, mozzarella, grated romano cheese, some olive oil, and a little more sea salt.
A little over 3 minutes cooking time.
