Scroll through cookware listings long enough and speckled gray-and-black pans start showing up everywhere, most carrying some version of the word "granite" in the title. It's a striking look — mottled, stone-like, a little more premium-feeling than a plain black nonstick skillet — and it's become one of the more recognizable design trends in mid-range cookware over the last several years. But the name raises a fair question before anyone adds one to a cart: is there actually granite in this pan, or is that just what the coating looks like?
