We've teamed up with Bake off Winner and TV chef Nadiya Hussain to bring you our cleverly designed steel bakeware & ovenware set - combining beauty with practicality . Every item has been created to make baking easier and more fun. Using a raised pattern on the cooking surface not only looks beautiful but it also provides added benefits of improved air flow and release . The gold non-stick coating on our bakeware items is the secret to perfect and even baking, whilst the black non-stick coating on our ovenware pieces - like this non-stick oven tray - holds and transfers the heat evenly for perfect roasting & browning. With this bakeware range, your baking skills will reach a whole a new level!
