Hard Anodised Oven Tray 43 x 31cm 5 "The best." Mrs Burke 16 March 2020 Over the years, I have purchased many oven trays. Some warped, others stuck fast to the food I was trying cook. All rubbish. Then I bought this one. What a game changer! Absolutely none stick, food just slides off. So easy to wash. It does say that it can be washed in the dishwasher, but there is no need. Worth paying a bit extra for a piece of kitchen equipment that will last a long long time.
