This is not my first pizza stone and not the first time I have used one on a grill. I have tried placing my old stone on the grill but, it never worked perfectly. It worked pretty good in the oven but, I had to cook it on the stone and then set the pizza on the highest rack for the residual heat to get the top nice and brown. This stone is not only thicker (5/8 instead of my old 3/8) it is elevated to allow more space away from the grates. I read the instructions about putting it on one side and using indirect heat. Sorry, that is not the way to get great results. Set it in the center of gas grill grates and set all burners to high. In 20-30 minutes it was screaming hot, around 700 degrees. I had the temp gauge pegged to the right. I am not even sure there is a need for the temp gauge. The extra heat coming up the sides of the stone, helps to cook the top of the pizza. My grill lid is double walled which may helps hold in the heat to cook the top. My first time using this stone I made four pizzas and they were unbelievably fantastic. I mean, wow! It cooked the crust perfectly and the top too. It cook evenly all over the top and bottom. This is far and away the best way to cook pizza. On top of it all, I get to use my grill and be outside. I think in the winter months, this will also work great in a gas oven, sitting directly on the floor of the oven with my other stone on the rack just above it. Hey, great sauce, toppings and dough are the other keys to great pizza but, getting it cooked right is just as important. I would highly recommend this to anyone trying to achieve that real pizza taste.
