If you are drawn to the beauty of stainless steel, yet are reluctant to sacrifice the cooking efficiency of aluminum, you can now have the very best of both worlds. A mirror polish stainless steel exterior, a heavy gauge conductive aluminum filling, and a satin finish stainless steel interior form a 3-ply disc. The disk is then formed into a pan shape, with walls and bottom of equal thickness, which allows heat to be conducted evenly. Glass lids allow you to monitor food and their domed design returns condensed moisture to foods. Stay cool handles feature an ergonomic design and secure attachment. A large sauce pan is very handy for soups, polenta, steaming veggies and a host of other tasks.
