Lisa, I think you understand by now you won some wonderful cookware. Cast iron cookware is kind of like "baking" - there are a few rules but once you know them the care and storage of them is a breeze.
If your Le Crueset is totally covered with enamel there is no seasoning involved. If you really, really, really hate them I'll pay for shipping and you can send them to me
(oh, that's my happy dance)
