No, this isn’t a cast iron thing. Using stainless pans, you can get nonstick effects that, in my experience, far outperform Teflon anyway. The process is called “spot seasoning.” I have cooked crispy, cheesy rice noodles with eggs with zero sticking.
I love my cast iron pans, but stainless is my daily go-to. Added bonus: use 100% copper wool to clean your stainless pan. The copper-coated wool at most grocery stores is problematic; you might get a few uses out of the coated garbage and then it starts shedding metal bits.
Pointing out inaccuracies and giving countrary opinions are fine, but calling OP disingenuous is calling them dishonest - and I don’t think you’re even using it correctly - the term usually implies that they’re playing dumb or innocent.
And this comment genuinely isn’t aimed at you, I’m just venting about people presuming to magically know somebody’s state of mind.
It seems like you’re making the assumption that in saying it’s disingenuous to make the claim, I’m casting some final moral judgment about the OP or their overall trustworthiness. Correct me if I’m wrong about that, you just seem to have taken issue with me potentially accidentally having called OP dishonest. To be clear, I was calling them dishonest (with regards to only the claim they made about their stainless steel pan being more nonstick than a nonstick pan, at least for the scope of my comment). It’s just patently untrue that a stainless steel pan is more nonstick than a Teflon nonstick pan, no matter what you do to the stainless steel pan (except applying a nonstick coating). I don’t have to make any unfounded assumptions about any mental state here. To make the claim requires that you are either innocently misinformed/uninformed or purposely making a misrepresentation about this particular issue.
And, for the record, I’m not assuming that the OP is malicious or intentionally set out to mislead people. It’s exciting to achieve little to no sticking in a stainless steel pan and you want to share that achievement with others, hopefully to encourage them to achieve the same thing. All I did was correct some innocent exaggeration. And if it was malicious, well, at least I still used disingenuous correctly.
