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.
As a wonderful cook, I resent just about every piece of cooking advice. They’re just oft-repeated, poorly-understood concepts.
For example, I love cast iron. It’s my go-to for nearly all my cooking. I cannot stand cast iron people. They think their lump of iron is a baby that needs to be spit polished and pampered like a Fabergé egg. No, you beat the ever-loving hell out of it, abuse it, soak it in water, leave it to rust, abuse it with scouring pads… then you rub a 1/16th tsp of oil on it and get on with life/cooking.
Edit: Same thing with knives. Before you give me a huge sermon about how to sharpen and care for knives, why don’t you understand that you can use a $5 German steel chef knife, a Rada quick sharp and a hone. For the amount most people cook and prep, that’s going to last 30 years. I cook every single meal from scratch, there’s 20,000 cutting board Kms on my $5 knife. Yet if the subject comes up, people are linking $300 knife reviews… Proof they want to have a knife, not use a knife.
