Fish fry is the non-stick test par excellence, after 2 months, burned black coating shows in the pan, which is impossible to remove, possibly with the orbital sander, and where the fish sticks. Also Silargan is here even worse, fish fry only works with classic non-stick pan or Neoflam, unfortunately there is not Amazon, but in hardware stores. Neoflam works already 3 months, looks like new, with no scratches. I assure to have written the article without conflicts of interest. Supplement 30.01.12: Once the pan was completely black occupied, I have this brave cleaned with a steel scraper (also Silargan pan), what can be done in 10-20 seconds just until now (about 3 months, once weekly cleaning scratches )) is in both after the surface like new and also not damage.
