What you need: 4 whole bricks + 2 half bricks + 1.5 8×16 pavers + 1 12×12 slate tile + a bbq OR some ingenuity and your own kickin’-around-masonry items. Or a quick visit to Home Depot. Basic concept: too damn hot to be baking pizzas in the house, so how can we get ‘er done on the grill? What doesn’t work: a bunch of standard 4×8 bricks laid on the grill to create a hearth/pizza stone. Tried it. As soon as I did it I realized why it was not going to work. No heat from above. Even with a bbq lid closed, no dice. What does work: good bed of hot coals, lay out the std bricks while it’s still damn hot, top with pavers to retain and reflect heat to the top of the pizza [let it heat up for a half hour or so at this point], and a tile of slate a few minutes before baking for a quick heat-up/transfer to crisp up the crust – which it did very nicely. A few hours later, it’s still 250-300 in there depending on location.
So there I have it. A little tide-me-over oven setup for the hot days of summer, until my large unit [yes, I used those words] gets built. Next time, I’m going to bake a few pizzas back to back. Photo of masonry layout below:
