I need to know where I made my pizza mistake!!! Last Friday I attempted to make my first "egg pizza", and although the top was cooked perfectly, the bottom was scorched- should the stone be heated or not??? The recipe in the box says no, but the recipes on this board say yes- I heated my stone. It could be that I only had the stone on top of the grlll face--- I'm not sure what the "bricks" are.....thanks in advance for any tips!!!
