Is anyone besides me thinking that you never cook anything evenly when the oven door is partly open? Has anyone used one of these? Seems to me to be a pretty expensive single-function device that, unless you eat pizza a LOT, would become a pain to find a storage space for.
The pizza stone is 13", so I would guess that is as large as you could go. The other model for sale has a stone that is 13.25" by 20", so you could make a larger rectangular shaped za on that one…
Orrrr just make pizza right on your grill. You could throw it right on the grates or buy a sheet of baking steel (better than pizza stone, more durable). Better temp control and multi-use.
Somewhere in an Atlanta suburb or at the Food Network studios Alton Brown cries a little tear every time someone spends 150 bucks on this unitasker.
Unless you live on a hacienda or you’re going to make home made pizzas on your camping trip, I can’t imagine that your kitchen oven is more than 50 feet from where you’d be placing this. There is a reason why the thing that Italian restaurants use is called a pizza oven and not a pizza grill. As others have suggested just buy a pizza stone and if you are dying to cook one a pizza outside put the stone on your grill.
