I had some buildup from smoking the turkey for Thanksgiving, so what better excuse to go nuclear and make pizza!
I went with PS feet down with stone on top. Worked great except when I went in to make the next pizza and the grill went chernoble. Luckily I just had to recalibrate my thermo.
The last few had burnt crusts. I think next time I'll put the PS feet up, put the grate on, and the stone. Likely will take longer to heat, but I'll avoid the direct heat to the PS and direct conduction to the stone. Here's some pics of the first one and a later one cooking on the egg.
