Well, that is the problem with fats. No long term storage. Only thing I can think of in TEOTWAWKI is to grow sunflowers etc. and make your own oil.
If we raised pork or chickens, it would be no problem. I have rendered fat from pork we bought in the crockpot. Then I stored it in the frig for a few months as I used it up.
The ghee will last quite a while too. I have several blocks of butter in the freezer. We stock EVOO, tallow, and ghee, but not as much as we’d like, because the shelf life is too short.
That’s true, with butchering animals there would be plenty of fat. I do have almond and hazelnut trees. Smushing them to get the oils might be a bit labor-intensive but at least if we eat them we will get the fullness that the oils will provide. Whatever word I’m looking for!
