FYI about those pans and reports in some reviews of black spots on the bottom, which some people might mistake for rust or stains.
Last night, I used my larger pan to roast a bunch of chicken wings with hot buffalo sauce--a naturally messy job.
After hand-washing and drying, I noticed little tiny black specks on the bottom of the pan.
It could be mistaken for rust or a stain.
However, I scraped at the little spots with my fingernail, and they popped right off. They apparently were little grease spots that I failed to wash off thoroughly.
Good news was that my fingernail scraping did NOT scratch the pan one bit. Still looks like new.
I still like the performance I'm getting from those baking pans.
