Don’t use chemical (Teflon) coated pots, no matter how good they are. Although Fissler uses its own patented coating, it still can’t escape the physical properties of the chemical coating (just like you are currently What happened) If you want a non-stick pan, I recommend WOLL, which has at least a physical coating and is physically non-stick. I currently use it at home, although I still use the original silicone spatula when cooking. Personally, I think the biggest advantage is that you can put cold water in directly after cooking. Rinse the chemically coated pot just after cooking. Do this a dozen times with cold water at high temperature and the coating will definitely come off.
