Help me, please. I just received this baker [?] as a gift, but I don't know what it is or how to use it. Can you tell me? It seems like a regular casserole or or baker yet it has a tall central post that is similar to a bundt pan or an angel food cake pan. But it's not a bundt pan because it has a lid and is rounded shaped, so that no cake could come out of the pan even when inverted. The central obstruction is open to the bottom of the baker, so this isn't a fanct "beer can chicken baker" or anything of that sort. I'd really appreciate any help you could offer me. That way I could thank the giver of this gift specifically, instead of simply thanking for that stoneware "thing"!
