storing peanut butter
my family always kept it in the cabinet but i've seen some people keep it in the fridge. what's best?
Though its not a 'must', I store all-natural peanut butters in the fridge so they won't separate. I hate the sloppy process of re-mixing the oil that rises to the top and the peanut-mass every time I use it. Regular ol' Skippy goes in the cabinet at my house.
The two deciding factors, I think, are whether it's one of the "natural" types or "commercial" (with stabilizers etc.) and how long it takes you to go through a jar.
Nut oils do turn rancid much faster than grain or olive oils, which is why it's often recommended to keep nut oils in the fridge. The commercial brands of peanut butter generally contain preservatives or at least stabilizers that slow this process dramatically. I've kept jars of Jif in the cupboard for months without any noticeable effects (yes, it starts to taste a little stale after a month or so, but it's not rancid).
But, for peaunt butter without any of those additives, I'd say that if it takes you more than a couple of weeks to go through it, keep it refrigerated to be on the safe side.
Now, as a disclaimer, I should add that I mostly cook with peanut butter; I don't eat it in sandwiches or anything. Maybe twice a year I eat a slice of toast with peanut butter, so maybe my standards are lower than those of people who eat it plain
I've had two jars of peanutbutter go rancid in the last couple of months. It is the cheap brand and that could have something to do with it.I have several jars in my storage and I hate to throw it out.
