I’ve never refrigerated peanut butter. Neither have I refrigerated ketchup, for that matter, though my ex-wife insisted that ketchup must be refrigerated. I acquiesced, just to keep family harmony. Now that she’s gone, I keep my ketchup at room temps.
Thing is, that peanut butter needs to be room temperature in order to be spreadable. And it keeps just fine at room temps in the cupboard. Brand names don’t matter; I get the local supermarket’s house brand, and it does just as well as any other.
I never had a problem with PB stored at room temp. Low water content, it’s just never gone bad for me, even after a year.
Ketchup OTOH has the water content to support some microbes. Back when fast food chains kept ketchup in table bottles, it was not unusual to get one that hadn’t been rotated and had gotten a bit fermented, a bit sour and boozy-tasting.
Chunky peanut butter here. Only the “ingredients: peanuts and salt” kind. No refrigeration. We do go through a jar in two weeks or so, so little time for it to go rancid.
Here’s a lengthy list of foods that don’t need to be refrigerated. I won’t vouch for its overall accuracy but it matches my knowledge of food safety fairly well.
It includes items like canned or jarred Peanut and other nut butters Beans and lentils Meat Tuna and other fish Hummus
In addition, this stuff doesn’t need it either, per the site. Soy sauce Ketchup Mustard Mayonnaise Salad dressings Honey Molasses Corn syrup
My peanut butter is just peanuts (site is English, but the preview is German). There is nothing about refrigerating it. It’s a 500g jar, which is less than a year old, and the expiration date is in October. It does say to stir it for maximum enjoyment. I stir it with a butter knife, which I then use for serving. I have never stored peanut butter in the refrigerator. Growing up, my neighbor had Adams peanut butter in the fridge, and it was in a big tub. Stirring it was hard work.
On the jar, in the ingredient list is only PEANUTS, which is written in all capital letters as it is a potential allergen. The warning is only for the potential allergens which are not listed in the ingredients, as it could contain traces of milk, lupin and sesame seeds.
I don’t refrigerate my Jif, and it doesn’t get rancid. It usually takes me months to go through a jar. It’s been a while since I’ve had Martin’s potato bread, so I think I’ll get some next time I go to the store so I can have a very nice PB&J sandwich.
Martin’s Potato Bread used to be my go-to, but then I discovered Pepperidge Farm Butter Bread. Oh my.
As for the thread topic, I’m a Jif guy, creamy, just the regular stuff. Until seeing and opening this thread just now, it had never entered my mind that anyone would ever refrigerate peanut butter. Just a completely foreign concept to me.
Technically none of those items needs to be refrigerated, correct. Well, you do need to refrigerate homemade mayonnaise, if you are one of those people that make it rather than buying it from a store. (I am not one of those people.)
However, I refrigerate all of them, because…
It extends the shelf life and freshness of all of them.
In each case, I prefer the taste of them cold.
None of those things harden or otherwise become difficult to prepare food with when cold.
I know some people prefer ketchup and mustard warm (as in not cold; room temperature), and I don’t have an issue with that. I use those condiments warm in restaurants all the time. No big deal. I just like them cold if I can help it.
Peanut butter in my experience doesn’t taste any better cold (again, personal preference) and can get stiffer (even the processed kind) so it stays in the pantry.
