I really thought that the lids were interchangeable on all pots/frying pans. Sadly they are not. I had bought a JC Penny Cooks set about 5 years or so ago and the lids fit all the frying pans -- I really though this one would do the same. The frying pans are all shallower than what I am accustomed to as well. I am happy with the set, but must remove one start for incompatible lids for the frying pans.
