Found an interesting mod
on a 22" kettle turned pizza oven.
"Part of what makes this open air culinary spectacle work is the heavily modded Webber 22.5" grill that's been outfitted with fireproof blocks and a domed top comprised of refactory cement and perlite that's been molded in the original Webber top. Using chunks of wood and charcoal, the Franken-Webber quickly reaches 1000F (the ideal temperature for cooking authentic Neopolitan-style pizza)."
My question is, why the heavy modification? Couldn't they just use a kettle and a pizza stone? Is it because of the high temps needed?
