Hard anodised is a super-durable material that ensures the pan heats evenly, while staying non-stick. It's so easy to clean, too. Designed by Jamie Oliver : “This is a great-quality saucepan, and whatever you’re cooking in it, from a quick tomato sauce to caramel, that non-stick coating really comes into its own. This one has measurements on the interior, which is very helpful when a recipe asks you to, say, reduce by half. Happy days!”
