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.
World is a better place when we dont buy pans that are designed to give you cancer and fail in a few years… Teflon is reserved for the 1-2 dishes that require non stick at a low temperature. The few dishes that I cant think of right now but i’m sure they’re out there.
You won’t find any disagreement from me there. I just think that when you set the expectation too high (stainless steel can actually be more nonstick than Teflon), people will give up and just go back to nonstick pans when they can’t achieve those results.
Regarding dishes that are solely the domain of Teflon, I think it definitely has a place for dishes that already have a high bar for execution. A perfect French omelette is hard enough on a nonstick that adding another layer of heat management puts it out of reach for most people. But like you said, there’s not much that I’d use Teflon for, so I just don’t have one after switching to induction.
