French Lyonnaise style frying pans, in 20cm, 24cm, 28cm, and 32cm diameters. I first came across these pans as a student working part time in busy professional kitchens - they were battered, slammed into ovens, under grills, thrown cold onto double burners blasting heat on full, thrust smoking under cold taps sending clouds of steam billowing to the ceiling, and no matter the tests, the abuse to which they were subjected they never, ever, failed. I decided then I would find these pans, for myself. Properly seasoned and prepared these pans will out-perform any non-stick or stainless pan, and cared for will last more than a lifetime. In seasoning the steel of the pan bonds to polymerised oil forming a deep brown to black surface that acts as a natural non-stick coating, one that does not peel if over heated (arguably it improves), self repairs if scratched (say by metal tools), will not release novel chemicals into your food, or for that matter poison birds. Made in Val-d'Ajol, France by de Buyer, who have been making similar pans in that region since 1830. All have triple riveted gunmetal enamelled steel (heat proof) handles whilst the largest has an additional welded looped handle to aid lifting. By tradition pan sizes equal the diameter across the top and not of the base. This might seem a cheat to some (or perhaps not if you consider a wok) but after some consideration we thought it best to stick with standard practice.
