Hey Trillium!! Your pan wasn't made by a company called Ruun, in Germany was it? I remember some years ago going to Alexander palace in Lond to a Big Craft and other stuff Fair with my friend Jacqui, and Ruun had these pans there and it didn't matter what they did to they, nothing ever stuck to them. They put an omellette in one with no fat at all, and no matter how long it was on the cooker, it never burnt, and the guy put sugar in there and cooked it and cooked it, left it for ages, tipped it out and when the pan cooled down, he just wiped it away with a piece of kitchen towel.
The pan I wanted was £75 without the lid, goodness knows what they are now if they still make them!
