We try and find the most durable cookware in the world. Here you can see the fruits of our labour so far - though we're always on the lookout for more. Our selection includes some cast iron lifetime guarantees.

To uncover the best pans, that you'll only need to buy once in a lifetime, demands that we follow strict rules. For both safety and longevity, artificial coatings are a big no. Mechanically, there should be as few joints as possible, with preference given to single-cast pans (meaning the handle joins the body rivet-free). The materials should be tried, tested and authentic. The best frying pan materials allow the pan to improve with age rather than degradate. And where possible, there should be a lifetime guarantee.
