The Viking 17pc 3-ply Clad Stainless Steel Cookware Set features three layers of stainless steel and aluminum to distribute heat evenly throughout the pan, sides included. The set features vented glass lids that make it easy to see what it happening during the cooking process while also reducing the chance of boil-overs. The interior of the saucepans and stock pots are marked with easy-to-use measurement markings so you know how much rice or liquid to add. The Pasta Strainer fits right into the 8 Qt. Stock Pot so that you can lift the cook pasta right out and strain it over the pan, keeping your pasta water hot to cook another batch or use for finishing a sauce. The Multipurpose Pasta insert is great for steaming shellfish, cooking seafood and much more. The Universal Steamer fits both the 2 Qt. and 3 Qt. Sauce Pan.The cookware features the signature Viking solid cast stainless steel handles that are riveted on with stainless steel rivets for a lifetime of us. The stainless steel pans are oven, grill, and broiler safe to 600 degrees Fahrenheit without the lid. The lids are oven safe to 350 degrees Fahrenheit, making it easy to finish a dish in the oven or even bake an entire casserole in the pan and take it right to the table for serving. All of the lids and cookware are dishwasher safe, but we always recommend handwashing to help maintain the mirror polished finish and extend the life of the cookware.
