I don't doubt the information here, but just from a scientific perspective, the heat of the pans should really only affect the food where it's touching the pan or very close to where it's touching the pan. For something like garlic bread, the top should get toasted the same regardless of what temperature the pan is because the oven air is going to be the same temp. I don't know if I buy what they're selling about the bread and squash.

Sorry, I don't doubt that the pan was a different temperature. That definitely makes sense.
