As a vegetable soup aficionado, I often make a large pot of soup and reheat portions as needed.  My cheap saucepan eventually warped to the point of uselessness (RIP).  Looking to replace the dead pan with a quality AMERICAN MADE stainless steel pan, I found All-Clad.  After reviewing the product lines and sizes I settled on the 1.5Qt D5 pan.  The size is perfect, it covers the small burner perfectly.  The feel, weight, and quality is amazing and the pan functions perfectly. Rainbow discoloration due to high heat on Chromium?  White vinegar removes it easily.  Science!
