“Butter lasts almost indefinitely in the freezer. I hear it’s possible to can it but had never done so myself.”
I didn’t know it lasted long in the freezer. I have a bunch in there that has already expired so I put it in vacuum bags hoping to make it last longer.
I did try canning butter last year! All the little Lids are still firmly planted. I used regular metal Lids instead of tattlers since the way they seal is just by Cooling. The Red Feather canned butter last 10 years so I suppose mine might last five.?
I ‘ve never had problems with the butter I freeze.
Whenever I get some out of the freezer, it thaws out just like it was when I bought it. Looks as fresh as can be.
I would still rotate the stock.
I think 5 yrs for sure on the home canned butter - the various ladies that I’ve seen who canned it have all said it would last at least 5 years.
