Don’t try this at home! Years ago, Paul had put some bread dough in a tupperware bowl and put it in the oven with the warning, “DON’T TURN THE OVEN ON!” Within minutes, I had forgotten, made a batch of cookies, and turned the oven on to preheat. This is the result (note the successful rising of the dough):
What is the next step when this happens? Turn the oven off, let it cool, and then snap the bowl off the the oven racks (not an easy task). But — I still have this work of art today, as friends attending our recent game night can attest.
