Lives there a cook whose heart beats so cold that he has not entertained dreams of building a wood-fired pizza oven in his backyard? Not in my house.
Just imagine summer evenings with friends gathered around the fire, shoveling in custom pizza after custom pizza, each emerging within a few minutes, blistered and browned on the top and with that perfect leopard-speckled char underneath — crispy, chewy and tender at the same time.
But when I broached the subject with my wife, who has already imposed a strict one-in/one-out moratorium on kitchen gadgets, she just laughed. How many toys would I need to get rid of to equal one pizza oven?
And when she found out that said pizza oven would cost as much as a small car, she positively howled. Cruel.
However, I have found an alternative. Granted, it doesn't have the architectural grandeur of the glorious oven I cooked in at a friend's house on the Palos Verdes Peninsula the other week. And I'll admit that the pizzas are not yet quite as foolproof.
But they're pretty danged close, and I put the whole thing together for about the price of a dinner at Mozza.
It's a gadget called the KettlePizza, and it fits over the top of the ubiquitous Weber grill. And after a little tweaking and a lot of learning curve, I have to say that it's kind of terrific.
You can order the KettlePizza from http://www.kettlepizza.com in various formats. The most basic includes a pizza stone and sleeve that fits over the grill, with a hemispherical cutout that lets you slide the pizzas in and out. This costs $150. Other formats are basically embellishments and range up to $400.
The operation is simple in outline but a bit more complicated in execution. You build a fire in the grill and arrange the coals in a C-shape. Add a couple of good-sized chunks of hardwood, and when those catch fire, place the sleeve on top with the pizza stone on the grill. Cover and wait until the fire gets really hot.
And it will. Using just this bare-bones setup, I got temperatures on the stone of more than 600 degrees (uh, I did have to buy an infrared thermometer — one of those guns that shoot a laser beam at a surface to measure the temperature; seriously, it was for science — and my wife was out of town).
That's way hotter than any home oven, but the pizzas still weren't as good as I'd hoped. So I took to the Internet, where there is an active cult of KettlePizza enthusiasts (there are more than 4,000 videos on YouTube). The high priest of this group is my old e-friend J. Kenji López-Alt, and his series of posts on the Serious Eats blog (www.seriouseats.com) should be required reading.
Following López-Alt's advice, I tweaked my KettlePizza by putting a second grill on top of the sleeve and using that to support a cover. I used the Baking Steel I'd ordered a couple of years ago for my kitchen oven, flanked by the 25-year-old quarry tiles I'd used for baking pizzas before that. (López-Alt, along with the designer of the Baking Steel and the designer of the KettlePizza have now teamed up for a deluxe package that will do all of this for you in a much more elegant build.… It's $400, with part of the proceeds going to charity.)
This arrangement reduces the volume of air that needs to be heated by the fire and also provides an upper radiant heat source to better cook the top of the pizza. In fact, the biggest problem I had after this tweak was that the oven was too hot — the pizzas cooked much more quickly than I was expecting (do not even think about getting a beer while the pizza is baking).
It took a few tries to get the process refined. But I am now able to maintain an oven temperature of 650 to 750 degrees for almost an hour before refueling and turn out pizzas that bake consistently in less than 5 minutes.
At least until I win the lottery, my pizza dreams are satisfied.
