TOUGH CONSTRUCTION: the anodising process makes this aluminium tray twice as strong as stainless steel, so it's ideal for daily use. TEFLON NON STICK COATING: the 3 layer Teflon Select non stick coating makes for effortless cleaning and food release. HEATS EVENLY: aluminium conducts heat evenly for reliably delicious cookies, chips and roasts, and can be used on the hob to make gravy.
