Whether you've got granite, wooden or laminated worktops, the one thing you can't afford to do is put scorching hot cookware straight down onto it. Which is why it will pay to have this heat-resistant insulated mat always ready on your counter. The dimpled metal surface dissipates heat very fast, coping with pots and pans at the highest cooking temperatures - and it's also big enough for the largest baking/roasting tray or a couple of casseroles at once.
