Le Creuset Professional Hard Anodised

WHAT IS HARD ANODISED ALUMINIUM?
Hard anodised cookware uses a unique combination of dual-layer materials: hard anodised aluminium on the outside, premium stainless steel on the inside. Le Creuset have continued their dual-layering throughout the whole saute pan to guarantee excellent heat conduction performance and prevent hot-spots. The hard anodised exterior is then finished with a durable non-stick coating for easy cleaning.
