I hope my suggestions will help you with your decision, while not cluttering your kitchen. Your answers will help you find what cookware will work most efficiently for you. I have been in homes where they have pots and pans of all shapes and sizes, but most of them are never used or improperly used. Remember, less is best. It is also not necessary to buy a cookware set.
Many manufacturers make better single pans than what the set has to offer.
Another thing to consider is the way the pots and pans will fit the burners on your stove. When they fit properly, you get an even heat with no hot spots. Some good names to remember when shopping for cookware are All-Clad, Calphalon, Cuisinart and Le Creuset. Remember also to buy the proper cooking utensils so you don't damage your cookware. I use lots of wooden spoons and make sure I have some great spatulas on hand.
