Unsalted butter

How long in fridge before it starts to go rancid?

  1. Weeks, months, especially if you keep it wrapped. It might pick up some off flavors but it won't go rancid. I wouldn't leave it out at room temp, though.

      Kept wrapped & in the fridge, I've NEVER had unsalted butter go bad. For quite a few months. I never buy salted anymore, because I really prefer to keep tabs on the salt that goes into my food, & every little bit helps. :)

        Agreed on all counts. I can taste such a difference in the two, and prefer the unsalted. I am totally not a salt lover.

        The only thing I miss salted butter on is crackers, and I rarely eat buttered crackers anymore anyway. Remember when they always gave you crackers and butter at restaurants, before they changed to serving warm bread? I loved those crackers!

          I definitely remember those crackers served with softened butter, & also loved them. In fact, my mother used to serve them as snacks. Of course this was long long before the cholesterol revolution hit.

          Lord - salted butter on Saltine crackers; my doctor would be epilectic over that - lol!

            Funny thing is, the butter and salt are actually all right, healthwise. It's the white flour and hydrogenated oils in the cracker that will get you!

            If your doctor actually knows these things, keep him/her.

    2. I never buy the stuff. I just use salted butter for cooking. I don't think it makes any difference.

          me too, maybe we should start a support group.

      1. It takes several weeks for me to through a pound, and I've never had it go bad. I buy one pound bricks for cooking, and don't take any special precautions to wrap it well. I also buy unsalted in quarters for table use which I keep longer, because I stock up when it's on sale. Never had a problem.

        1. Several weeks, but not as long as salted. We generally have unsalted in the fridge, in preference to salted as it's more versatile.

            Pack we've got at present has a use-by date of 2/7/12. I reckon we've had it for a couple of weeks.

          2. I would say two to three weeks for best quality, but it can still be eaten for several weeks after that. Salted butter lasts much longer, because salt acts as a preservative. Butter freezes well, so if you're not using it up fast enough, just take out a portion and keep the rest in the freezer in a freezer bag with the air squeezed out.

              We buy only salted butter and keep all but one stick at the time in the freezer. One stick will "thaw" very quickly on the counter or for cooking you can cut off a hunk straight out of the freezer.

            2. I have had it for weeks and months and never had it go bad if stored in the refrigerator. it is obvious by smell if it goes rancid, so I have no problem using past any suggested use by date.

                Yes - rancid fats of ANY type have an umistakeable odor. Once you've smelled or tasted it, you'll never forget it.
