Lynn Pardy wrote on this site sometime ago about the nesting cookware. I bought the teflon interior version and wish I had bought an extra frying pan. This is great stuff and she said she had found it on the internet for under $100! Great stuff! However, I have an old aluminium dutch
oven that I have cleaned with salt water and no problem, plus cooked with salt water for pasta and had no problem. Plus, I still use a 10 inch cast iron skillet to cook and with the same care my Grandmother used on the same pan, it has never shown a spec of rust.
