How to Hack Your Grill Into a Superior Pizza Oven – Seattle Food Geek

update : Andris Lagsdin, fan of Modernist Cuisine and steel technical has precisely launched a Kickstarter for Baking Steel, a low-cost slab of pre-cut sword for baking pizza and breads in just the room I describe below ! I ’ ve tested one of his prototype units and it performs like a champ – even with a unmarried Baking Steel ( no bus ) I was able to produce fantastic, wood-fired-oven-like results on my grill ! I highly recommend this Kickstarter for anyone looking to make pizza or breads at family .
The guys from Tested.com came to Seattle, so I shared with them one of the projects that ’ south been on my mind recently : making perfect pizza at base. In a previous mail, I discussed my approach to making great pizza boodle. But, boodle is entirely one half of the equality. Without a estimable oven, the best boodle in the world still won ’ thyroxine produce quality pizza .
now, let me first say that there are people who devote their entire lives to pizza ovens – to building them, to studying them, and to understanding how they work. I am not one of those people, and, although I still have a blank space in my thousand that I one day hope to fill with an actual pizza oven, my finish here was to produce the best pizza possible using my CharBroil infrared grill as a start point. But if you want to send me a pizza oven, I ’ ll screen the asshole out of it.

There are two keys to hacking a grill into an effective pizza oven : getting it in truth goddamned hot, and holding the heat. Getting a grillroom hot is not sol much of a challenge – add enough charcoal and let it burn for hanker enough, and you ’ ll have quite an hell. Add more airflow or extra oxygen, and your fire will burn hot and fast. But, retaining that high heat when you open the hat or add cold food… well, that requires multitude .

Physics Interlude!

Mass, like a pizza stone, or the thickly floor of a pizza oven, or in this casing, 25-lb steel plates, dissemble like a heat battery, storing up heat energy. I was first turned on to the estimate of using sword alternatively of ceramic brick by Modernist Cuisine, who recommend the proficiency not alone for grills but for family ovens ampere well. sol, why are sword plates better than a pizza stone ? A few reasons :

  1. Steel is much denser than ceramic materials.  A typical pizza stone has a a density of 0.0625 lbs. per cubic inch.  The steel plates I’m using have a density of 0.329 lbs. per cubic inch – about 5 times as dense.  That means that for the same volume of material, I can store much more energy in steel than brick.
  2. Steel has a much lower specific heat than brick.  This means that it takes less energy to heat a steel block than a brick of equal mass.  So, the steel will heat up faster in the oven.
  3. Steel has a much higher thermal conductivity than brick.  Thermal conductivity measures how quickly heat moves through a material, or between materials via conduction. This means that the heat can move from the steel plate to the pizza crust faster than it could if I were using a ceramic material.

All of these factors are summed up in one commodious quantify, known as thermal diffusivity. And, it turns out that the thermal diffusivity of 304 sword ( the grad I ’ thousand using ) is about ten times greater than the thermal diffusivity of brick. [ I don ’ t have accurate numbers for the ceramic writing of pizza stones specifically, but it will be alike in magnitude. Some types of sword, like high-carbon sword, have more than 20 times the thermal diffusivity of brick. ]
Do ceramic pizza stones produce fine-looking, big tasting pizza ? Yes, absolutely. But according to physics, they necessarily do so more slowly than steel. One of my pizza criteria is a crunchy crust that will support its own weight when restrain from one conclusion. I ’ ve found great success in achieving this texture with a steel cooking surface. The other advantage to steel, of path, is that it will death closely everlastingly. I don ’ t have to worry about dropping and shattering it, I can use it as a griddle and scrape it clean, and if I need to build an impromptu blast shield, I ’ thousand all arrange .

To hack your grill into a worthy pizza oven, here’s what you’ll need:

To assemble your pizza oven :

  1. Place one of the stainless plates in a corner of your grill. 
  2. Place two of the stainless steel pipe segments on the two far corners of the plate.  Place the other two pipe segments on opposite edges of the plate, about 1/3 of the way back.  These pipe segments will hold up the top plate.  By pushing them back from the front corners, you allow yourself a little more room to negotiate the pizza with the peel.
  3. Place the top plate on top of the pipe segments.  It should sit firmly – you sure don’t want it crashing down on you during cooking.
  4. Install your BBQ grill fan or bellows on the opposite side of the grill, above the open grilling area not covered by the steel.
  5. If your grill has a charcoal tray or basin on the open side, fill it with charcoal.  If not, place the charcoal in a roasting pan or metal dish on that side of the grill.  Ignite the charcoal, turn on all of the burners and close the lid.  Allow the grill 45-60 minutes to preheat thoroughly. 
  6. A few minutes before cooking, start your grill fan or bellows.  This will boost the internal temperature of the grill and even out hot and cold spots.  A cooking temperature between 800°F and 900°F is ideal.
  7. Just before cooking, turn the burners below your steel plate down to 75% power.  This will help prevent the bottom crust from burning before the top crust is fully cooked.  However, I’ve found that the first pizza of the day is usually somewhat sacrificial 🙂
  8. Slide your pizza onto the bottom steel plate and cook, turning once, for 2-3 minutes or until the cheese is melted and the top crust is golden brown.  Keep the grill lid closed as much as possible during cooking to maintain the high temperature.
  9. Enjoy extraordinary pizza made at home!

I hope you enjoy the joy of homemade pizza ampere a lot as I have. I ’ ve probably made 50 or indeed pizza this summer, and there is nothing quite as satisfying than pulling a perfect pizza out of the grillroom and serving it to friends. If you don ’ deoxythymidine monophosphate ( or can ’ thymine ) have a grill, this technique works pretty well in a home oven, excessively. Place one steel plate on the penetrate floor of your oven to act as a estrus battery. Set the other on the top rack. Preheat your oven for an hour on its highest temperature setting. You ’ ll need to add a infinitesimal or two to the bake time, but the results will be worth it !
