I have inherited, from my folks' house, two sets of cornbread skillets. They have six corn shaped depressions in them, made of cast iron. I don't remember my Granny using them, but I know that they came from her house after she passed in 1976. I can remember my mom trying to use them in the oven but the cornbread stuck to the insides. Is that how you used it or do you use in on the stove top? Just wondering. They are pretty neat, that's why I snagged them.
