This MasterClass Bundle allows you to effortlessly achieve superior roasting and baking every time. Their heavy duty construction and state-of-the-art non-stick coating are perfect for daily use. They are manufactured from heavy duty 1 mm commercial grade carbon steel that's been electroplated to give additional strength. This allows them to absorb and distribute the heat from your oven more evenly. With this, they consistently provide you with superior results - with not an undercooked cake centre or unevenly cooked joint of meat in sight. All items have a non-stick coating, free of chemicals such as polytetrafluoroethylene (PTFE), perfluorooctanoic acid (PFOA) and bisphenol A (BPA). So not only are they designed to deliver quality results every time, theyre a safe choice to cook or bake with too!
