A while back I recall a thread about waterless cookware. Yesterday I was in Duluth and went to my best friends estate sale, she passed 5 weeks ago. Not too long ago she had bought a set of Cordon Bleu cookware and loved it. Well now I have it and am intrigued. Any information of suggestions on this stuff? Also, what is the piece with the holes in it, it fits over the top of of one of the pans. Here is a pic of one of the pieces.
