One method is to use the plate setter upside down then placing a stone on top of the place setter. I use the 3 feet that came with the Egg on top of the place setter and then the pizza stone (this leaves a small space between the place setter and the stone. I cook my pizza at 550 degrees. This takes about 8-10 minutes- cook until the crust and cheese start browning. M
I know some Eggers prefer paper and others use corn meal and a paddle. Technique only.
The Naked Whiz at his recipe site has what he calls random bits of information on making pizza in a ceramic charcoal cooker that may help out also.
