I’ve heard from several sources that the iron is supposed to be good for the diet. I love my carbon steel and cast iron kitchenware. All of the studies I’ve seen show it as a superior option to PFAS cookware and will still outlast the latest ceramic options. I have a very non-stick carbon steel pan and griddle from avocado oil seasoning.

You didn’t mention that you’re oiling it after drying it. It’s recommended that you lightly oil the surface upon storage.

I think cast iron will definitely outlast ANY non-stick, no question. For non-stickiness though it’s basically on the tolerable end - put oil in it and most stuff will slide around but sometimes you don’t want too much oil so its a trade off. I think stainless steel is a great option in its own right - it’s not really non stick but it can be made tolerable with oil and can be scrubbed back to condition and thrown in the dishwasher.

I sometimes coat my cast iron pan in oil, but more often than not I don’t.
