Maybe I need more oil on the pan. The brick came out pretty easily, but left a layer on the pan...
...cemented on.
It crumbled all over and I took it to the garbage outside to break up, but the middle did not break easily. I did not attempt to torture test it, I broke off what came easily, and that is what is left.
Actually rectangular pans, more oil, and trying to leave it higher in the middle?
At what point should I be able to turn it over?
