Tried grilling pizza last night for the first time with my new Weber Pizza Stone. A disaster! I read on the forums that most use corn meal so the pizza doesn't stick. Well, all we had on hand was corn meal mix which is corn meal with flour. Burnt the crust like a sum beach. What wasn't burnt tasted really good with the mesquite wood flavor. I did put the mix on the pizza stone and on the pizza paddle.
Read a little more on the forum and learned that I should have put the coals around the perimeter of the grill rather than in the middle and right under the stone. Temps were up to 600 degrees. Question, will the straight corn meal burn as well? Should I not put any on the stone itself?
Thanks
The corn meal is to keep the pizza from sticking to the peel, not the stone.
Its much like throwing raw chicken on cast iron. stick or not once it cooks up a bit it will loosen... But with insufficient corn meal when you go to launch the pizza of the peel it will deform and stick like a mother...
In my experience... which is MOSTLY oven, as well as some propane turkey fryer burner... The corn meal wont really burn until you take the pizza off of it. When the pizza is on the corn meal it will take enough energy from the corn meal to keep it from burning.
When the bottom of the pizza burns, it is just indicative of the biggest challenge... Heating the top.
IMO two things are important. 1) Don't heat the stone directly from below. It will get too hot, and the air above will not get how enough 2) Direct the hot air flow across the top of the pizza.
Stone temps will depend on your dough/flour/pizza style choices. I like a neapolitan pizza which requires something more like 600-700 temps. Its great if you can use an IR thermometer. If you have harbor freight near you you can almost always find 20% off coupons online, and get one for $20-$25.
I would put the fire on the back side of the kettle, the stone on the front... Leave the vent lid closed and set the lid slightly askew, so that there is a gap in front of the stone. look for a gap large enough for a standing flame. This will allow the fire to burn in the back, and will force the air to exhaust out the front, just over the top of the pizza... Keeping the stream of hot air flowing over the top of the pizza to help even cooking. This is basically what kettle pizza does. This pattern of airflow from beneath and behind the stone over the top is important in my experience.
