Other than Okra, we cook most everything in cast iron.
Lot's of good suggestions here. Not gonna argue with folks of what or how to care for cast iron.
I have re-seasoned an 80 year old iron scotch bowl for my son in law now 5 times. Kid is determined to clean the damn pot with salt. Apparently folks from Georgia clean cast iron with salt.
Down here in Louisiana, we clean cast with elbow grease and hot water.
Any ways..............check into some of the newer products like CrissBEE.
It's beeswax and oil base, goes on easy, VERY little goes a long way.
I have cast that literally is in my last will and testament.
