Vent: I spent 5 years storing my cast iron skillet completely wrong
Back in 2017, I thought drying my cast iron with a dish towel was fine, not realizing I was trapping tiny bits of moisture that caused rust spots over time. A cook at a diner in Cleveland showed me how she heats it on the stove for 2 minutes after washing to evaporate every drop, and I felt like an idiot for all those ruined pans. Anyone else have a basic kitchen habit they didn't learn until way later?
Wait, is your grandma using a gas stove? Because gas stoves heat up way faster than electric or induction, so by the time she cracks the egg the pan might already be hot without her realizing it. I used to think the same thing until I switched apartments and suddenly my eggs were a disaster. The moisture thing with drying is real too, I actually ruined a vintage pan that way and felt so dumb when I learned about the stovetop drying trick. Your grandma probably has it down to muscle memory where the heat is perfect without her even thinking about it.
Wait, is preheating actually that important? My grandma always threw cold eggs into a cold pan with butter and they came out perfect, no sticking at all. I think the real trick is just using enough fat and not messing with them too much before they set.
