Does anyone know the actual shelf life of bacon grease, both refrigerated and left out on the counter next to the stove? Does straining or filtering have any effect?
Googling brings answers varying from 3 days to around 100 years, a variance which doesn’t give me a lot of confidence about their veracity. I was raised on products cooked in bacon grease of various ages, with no ill effects, but I don’t know if that’s normal or if I was a lucky individual.
PS - Yes, I’m fully aware of the health hazards of bacon grease even when freshly recovered from a slab of bacon, so consider this question to be for purely scientific purposes if you wish.
