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.
I’ve cooked every meal from scratch for 5 years
There’s one tool that was worth the $50 and that was a garlic press, the rest was money wasted
It’s much better to understand your tools and buy appropriately, instead of just assuming that lots of money is the answer
That’s my opinion and experience
