I use my griddle for pancakes. Ok, once I broiled fish on it, but otherwise it's only for pancakes, and we make them a lot! In the past, I've used a non-stick aluminum griddle and a cast iron griddle. I didn't like the non-stick finish and, even with oven pre-heating, the cast iron is still too uneven. I know there are companies like Storm Copper where one can buy a pre-cut piece of copper sheet stock. I could get stock up to 1/4" thick if I wanted. And I suppose I could always have a piece of sheet stock tinned on one side. Since I don't need a griddle with a lip around the edge, would making a copper griddle this way present any problems or issues? Thanks!
