I really don't know much about Cast Iron cook ware, that's a world unto it's own.......I do have ample experiance indeed of scrubbing my Mom's Black Iron frypans and such........A Georgia Girl always makes chicken in a Black Iron Skillet..............
The "Official" moderator of this thread is a Black Iron Guru...........But, he's busy trying to get a new home to the liveable level, got his hands full right now, don't post much................
I'm very happy that your meal turned out so well...........See, it ain't all that tough..............

I remember my Mom getting a crust on her chicken in a black iron pan, that that's all I wanted to chew on, the burned parts...........
It's a shame I haven't any black iron cookware........well, what I have is ceramic coated..........it's different..............
