I can't cook on teflon and I won't. Plastic turners (I call 'em spatulas) are not allowed in my kitchen. I do use olive oil on my cast iron, but only after it has been well seasoned with bacon grease or vegetable lard. Whenever I have a little bacon grease left over, I rub down all my cast iron, top, bottom and handles. I always oil (whatever oil is on hand) my pans after using them and I never have a problem with things sticking like eggs. I also like to clean the pans out while they are still warm. If there is any left overs, I let the dogs clean them, then I sterilize them on the stove and oil them before putting them away. The worst thing I've ever done to cast iron, was putting my 7 quart pot on the wood stove as a steamer. How do you keep a steamer from rusting?
I have a flipper griddle, it has a crack in it, but works great, it is too small for most of the cooking I do. I wish I had a couple of ol'tyme griddles like in the first posting! I've been using an old cast aluminum griddle salvage off an early gas stove. It works well, and I treat it like cast iron.
