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.
Recipe:
1 egg 3/4 cup of your favorite oil 1 medium banana 1 pinch lemon zest
Put oil in pan over medium high heat until oil just smokes, allow to smoke for 15 seconds, then reduce temperature to “egg making temperature”. Add egg. Burn the shit out of that innocent bastard and push it around while repeating “egg slide freely!”. Remove your egg with a crispy, brown bottom and wet, runny whites from the skillet. Reserve oil.
Into one large coffee mug, pour your oil, add lemon zest.
Last, throw all this in the trash with your Teflon skillet, and eat the banana.
