PSA: That 'season it in the oven for an hour' advice ruined my grandma's pan, and I'm done pretending it's the only way
I was at the Portland antique show last Saturday and watched a vendor pull a beautiful 1930s Griswold out of a lye bath, then tell a young couple they had to bake it at 500 degrees for a full hour with flaxseed oil or it was junk. I've been cooking on cast iron for 22 years and I've never once put a pan in the oven to season it. My grandma's pan, which I still use daily, was seasoned on a wood stove in Kentucky with bacon grease and a rag, and the slick black surface puts any oven-baked pan to shame. The real trick is thin layers of any fat over medium heat on the stovetop, not a 500 degree blast that just makes smoke and flaky patches. Does anyone else here still season on the burner, or am I the last one holding out?
The "thin layers of any fat over medium heat" part is the whole ballgame and people skip right over it. Every layer you put on the stove is a layer you actually watched bond to the metal, so you know it took. Toss it in a 500 degree oven and you have no idea what's happening in there, you just hope and pull out a pan with sticky brown patches that flake into your eggs. My grandma did the same thing on a wood stove, bacon grease and an old rag, and that pan is glass after 60 years. Slow and thin beats hot and fast every single time.
