I'd bet the majority of iron skillets in people's lives have rusted and been binned. I think it's the few rather than the many that take/have the time to scour and "season" them. Stainless steel, on the other hand: never had to do more than wash it with a sponge. Still shines, still smells clean.
Yeah all those decades-old cast iron skillets have just corroded away to nothing, haven't they ;)
Thanks OP! Bought the 5L with discount code! Going to smash out alot of batch cooking with this 8)
