EXCEPTIONAL NON STICK: with 2 layers of Quantum II non stick, this lidded roasting tin releases food easily and cleans in seconds. SELF BASTING LID: indents in the lid drip moisture back into the pan, for extra-succulent roast meats and rich, flavoursome casseroles. SUPREME PERFORMANCE: 1mm thick carbon steel ensures smooth heat transfer, while its sandblasted surface improves non stick adhesion. USEFUL INFO: these MasterClass roasting tins are 100% BPA, PTFE and PFOA free, warp resistant, dishwasher safe, and oven safe to 220C.
