I recently came into possession of a 12" cast iron skillet that's been in my wife's family for years. And by 12", I mean the inside of the bottom is 12", the outside of the top must be 17". It's huge, but not in the greatest shape. They used to use it on a campfire next to the fishing stream at their club in PA. It's been in the basement for 25+ years and has a little rust and pitting on the bottom, but the inside is smooth as a baby's butt. I'm going to run it through the self cleaning cycle in my oven tonight and tomorrow begin the Flax oil seasoning process.
