Do you have a flattop stove? I really like how easy my flattop stove is to keep clean. What kind of pots work well on a flattop? I need to replace my pots with ones that have a perfectly flat bottom. And I am trying to not use nonstick coated pots. I looked at All-Clad at the store and they seem to be very flat and made in USA. Does anyone use All-Clad pots? They have several choices in their brand.
