Ok, have seen this mentioned but I did a search and come up with nothing. I have a set of four stainless steel pots and pans I purchased at Dehillerin in Paris about 8 years ago (before I knew enough to look for an aluminum or copper layer). They are thick, high quality stainless steel with brass handles and have no identification except for a "made in france" stamp. They have been great but I get hot spots and have trouble with uneven cooking. I've got a common cheap gas range.
I would love to have aluminum discs bonded to these pans for more even heating but I can't find a source. They have some sentimental value, so I wouldn't mind spending some cash to do this. Any ideas? Thanks!
