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.
Bought a carbon steel pan - never looked back, it is excellent and lasts forever!
Got one too, searing steacks is wonderful but I sure can’t make eggs without garbling them!
I have a well seasoned good quality one that makes eggs as well as a nonstick pan. Took time to get to that point though. Sugary American bacon is the surest way to end up having to reseason it though.
