Say goodbye to baking sheet hot spots. From masterclass's award winning bakeware collection, this baking sheet tray uses two layers to create an insulating effect. This allows heat to distribute more evenly throughout food, for more evenly cooked and baked results. Each of these layers is manufactured from heavy duty carbon steel. This means there's no warping. They're also electroplated, for added resistance against rust. The sheet is oven safe to 220 degreec 428 degreef, so you can rely on this reusable baking sheet time and time again. Delicate baked foods, from cookies to macarons, are easy to remove from the tray's flat surface. It's finished with a double layer of quantum ii. This powerful non stick coating releases food instantly, so you can simply slide your bakes off onto a cooling rack. It's totally free from pfoa, ptfe and bpa too. With its flat surface and 35 x 28 cm 14 x 11 inch size, it's versatile and a good fit for most household ovens. Bake gingerbread, ciabatta, meringues and more. Once you've finished, you can simply pop it in the dishwasher for a fast, effective clean up. Winner: bakeware best of best sellers, housewares magazine, 2013, 2014, 2015
