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 bought two a couple of months ago and I am never going back to anything else.
If you have a strong burner, the recommended carbon steel wok works great too, even on my electric stove. Im stunned at how fast it heats up and what a good job it does even in my inexperienced hands.
Kenji, a serious eats alumni, has an award winning wok book I picked up at the same time. It’s a beast, covering tons of different cuisine and methods. Really great combo.
