Recently we moved house, and took it as an excuse to ditch a bunch of old and dying roasting pans.
We kept some glass trays (suitable for cooking in) though, and have ended up using them for just about all our oven cooking. On the top I still use either the steel covered copper bottomed things or cast iron cookware, but in the over it's mainly the glass.
Everything seems to turn out just fine - am I missing something? Committing a heinous sin I've somehow forgotten? Do I need to run back to buying some proper metal roasting trays?
