Not just one potholder. TWO OR THREE.
Most people don’t ever cook at 500 degrees, so they think a standard potholder will work. Not even close.
to slip over the pan's handle; one pot holder over that does the trick.
And folks, PLEASE remember to warn EVERYONE in the kitchen about that frying pan when you take it out of the oven and place it on the stove or a trivet about how hot it is. I warn my wife each time I take it out of the oven, and keep the sleeve on the handle. If you have several people in and out of your kitchen, place a warning sign next to pan. If they grab that handle, they lose all the skin on their hand.
