Chef-designed and kitchen-proven with sustainability at the core, Thomas Keller's tri-ply clad Insignia Stainless Steel Cookware Set raises the bar for professional culinary performance with purpose-built cookware focused on exceptional results while remaining eco-friendly. Designed by Chef Keller, the Insignia collection boasts bespoke handles to rest comfortably in your hand, significantly reduce heat transfer with the thoughtfully placed heat vent, and are seamlessly fastened to the pots and pans to eliminate one of the hardest to clean crevices. The triple-bonded 18/10 stainless-steel construction featuring Hestan's exclusive ProCore aluminum delivers 35% greater heat conductivity. That means faster, more consistent heating, plus faster recovery time to stay in control of temperature and timing. In addition, you'll find that the saute pans, sauce pots, rondeau, saucier, and stockpot are wider, not taller, to increase cooking surface for better heating, browning, and enhanced flavor. The set also contains an 8.5" saute pan (oven safe to 500°F) that is finished with Titum nonstick, multi-layer system - the world's most durable nonstick. Completing this assortment of pots and pans, are two universal lids (made in Thailand) with Insignia steam vents to reduce boil overs, pressure, and eliminate rattling. Durable, innovative sealed rims make this thoughtfully crafted cookware set 100% dishwasher safe, while purposeful engineering accommodates a wide range of culinary needs including oven and broil safe to 600°F.
