How to take care of the teflon coated cookware to ensure their long life?
Be very careful heating it

Usually with a steel or iron pan I'll crank the heat under it and go do something else for a couple of minutes while it gets up to temperature. If it takes me five minutes to get back to it, maybe it's a little too hot and I have to hold it away from the burner for a few seconds before adding the oil. With teflon, that can damage the pan, so I keep a closer eye on it and hold my hand over the pan more often to see if its ready.
