They look good. I've been meaning to try this for a while. I would think that the crust would burn before the cheese melted too. Does the direct heat change anything with the way you use the pizza stone?Looks tasty! My efforts at pizza on the grill were a dismal failure. How hot and how long?
tried to keep it up around 500, or as hot as 2 burners out of three couild get it. took about 5-8 minutes per pie. I put a pie on, went and stretched and topped another, put that one on, stretch, top and then pull the first one off. got to get the dough really thin so it cooks quickly enough.
