Cast iron is cheap, indestructible, gets better with time, does want some care but nothing outrageous. I do have a good stainless skillet as well, call it the "stick pan", if you want something to stick and then deglaze, it's good.
But the cast iron is my joy, my kids joke that I love it more than I love them (it is older than they are) and already argue about who will get it when I die. Have never bought a nonstick pan, they seem unhealthy, and old cast iron is satiny and nonstick. It suits the way I cook, or perhaps the way I cook has been shaped by the pans. I don't worry about tomatoes or wine sauce but wouldn't slow cook spaghetti sauce in one, would use stainless or the Le Cruset one for that.
Mostly I think it's like flannel, not great at the start but improves with use, ends up better than everything else and then stays better for a long time. In the case of cast iron that could be several generations.
Nooo give it to a disapproving hipster dude, so he can sand it and lovingly restore it and judge you!
One of mine got crusty, I put it in the oven and ran it through a self clean cycle, it all burned off and I re-seasoned it, been smooth sailing since. So you could try setting it on fire like that.
Tue secret to cast iron is fire.
I know everyone talks about their tricks but mone has mostly just been lots of heat directly applied to it and then slap cheap oil and rub it with a rag I accidentally set on fire once and then back to the flame. I figure it worked for my ancestors. And they seasoned that shit with sunlight.
Find someone with a self clean oven. My current one doesn't do it either but the ones made to burn the baked on grease to ash get up to 475-480, that is what will burn off the seasoning. Not as hot as a kiln, I have no Idea what that would do.
