This hard anodised tray is extremely hardwearing and suitable for a lifetime of use. The light weight aluminum is given an electrochemical treatment which provides extreme hardness and the aluminum ensures that the cooking process is very efficient and even. The internal surfaces of the tray are finished with a Teflon non-stick coating, making it easy to clean. Please note that because of the hard anodising process, trays may differ in finish and if washed in the dishwasher, the outside of the tray may change colour, but this will not in anyway affect the performance of the tray. The tray can be used in the oven or on the hob and fits the runners of the Everhot cooker top oven perfectly. The Everhot Chrome Grill Rack can be bought separately to fit this tray.
