I found these stashed away, and decided to clean them up season them because they are cast iron and need to be seasoned of course...I used them for making corn bread muffins in, I used them often when the kids were small..They loved eating fish shaped muffins. The fish pan is newer and was not used as much as the corn shaped pan, which is why the corn pan is so black. The fish pan will turn dark in time...If I use it enough. I probably won't use them a lot but I am glad to have found them again.
