We did pizza on the kettle for the third time tonight, all the bugs are worked out .
For sure get some of the mesh pizza pans. We build our pies right on them, after about 5 mins of cooking they come right off and then you can put them on the stone with out the pan.
We have an aluminum peel and it works great. We stopped using the corn meal, don't need it.
Don't give up, and even the mistakes are yummy!
