There might be better things now, the various seed oils, but folks been curing with rendered fat or regular animal grease of some sort for decades with satisfactory results long before any seed extracts were around I suspect.
Lard. Case closed.
Since Egyptians were using flaxseed oil when preparing mummies I suggest your suspicion is off by a several millenia...
Ouch, bit by early history, thanks for learning me something. But, I did say decades, not millenia. LOL Just joking around. Though my grandmother & probably great & great great didn't likely know or have access to seed oils,,, they got by, well. Some beautiful, extremely useable cast skillets seen all over before the post war aluminum & teflon craze.
