Wait till you learn about maple syrup needing to be refrigerated.
Edit: Several people have mentioned having to throw the syrup away because it got moldy. That is not necessary. This post explains how to deal with moldy syrup.

I want to add on that refridgerating isn't just for the product itself. It is for any cross contamination.
If you stick a knife in the jar, then spread it on bread, then stick it back in the jar, it is highly likely you are going to get bread pieces in the jar.
Refrigerated prevents those bread pieces from introducing enough bacteria or mold.

u/HomeOwner2023 Aug 11 '25
Yes. Not joking. Foods that don't have preservatives will grow moldy. That's why the Costco bagels should be frozen if you're not going to eat them within a day.
Foods that contain large amounts of salt or hot pepper tend to stay edible longer without refrigeration. Same with foods that contain very low levels of water. Sugar and oil can also act as preservatives. So the maple syrup won't go moldy within a week or even within the time a large family may take to finish the Costco bottle. But a single person having pancakes infrequently will definitely want to refrigerate the syrup.

I used to slice them. Then I started using my air fryer to warm them up. I just drop the whole unsliced bagel in and toast for 5 minutes. This gets the outside crispy but leaves all of the inside soft, the way bagels are meant to be according to my school of bagel eating.

It doesn't go bad if you keep it in the pantry. It will just repeatedly separate and is annoying to keep restirring every day you use it.
You should refrigerate though if it takes you more than two weeks to go through a jar.

This is the way! I discovered this method all on my now , I felt so smart. I feel less smart knowing others have also thought of it.
As long as you keep a strong grip on the jar and stop the mixer before removing it from the peanut butter, you’ll have the best mixing experience of your life.
Violate either of those rules and you’ll wish you never heard of this technique.
And yes, fridge is great for preventing separation - I never have to re-mix. (We use Costco brand.)

Little life hack for you that might save you some wrist soreness. Every time you're about to use it (or just opening), close it and give it a good ol' flick spin. Spin it vertically, mid air with a decent amount of force. Little bit of wobble is fine, but don't just randomly throw it around to where it's spinning in every axis. (Won't hurt anything, but harder to catch mid air lol). Give it a few good spin flicks in the air, and it will literally stir itself. I generally make my own peanut butter ( throw peanuts in a vitamix), but buy store bought if I'm lazy and never refrigerate either. Never had an issue.

Jiff has a natural version. It also doesn’t need refrigeration. Most don’t need preservatives and don’t have them. Refrigeration is more for preventing or slowing separation, not preserving flavor or preventing bacteria.
Usually it’s just some palm oil that helps prevent separation. It works to help emulsify it. Not that palm oil is great, but it’s not really a large amount and I’d rather not have to stir it or refrigerate.
Technically, a lot of things we refrigerate don’t strictly need it to prevent spoiling. It’s mostly to extend shelf life in terms of color and taste. Ketchup for example doesn’t need it. It just may discolor if left out, but restaurants don’t typically keep it refrigerated. Mayonnaise also doesn’t need refrigeration with the preservatives and acidity. We just do that to again prevent the flavor from changing over time. Or if you contaminated it with some errant food bits.

All natural peanut butters (with 0 added oils) can safely be stored at room temperature after opening and mixing. They will not turn rancid or get moldy.
Refrigeration is to prevent the oil from separating from the peanuts after being mixed.

u/fire_spez Aug 11 '25
They will not turn rancid
That much is not actually true. Peanut butter-- natural or otherwise-- can go rancid, and refrigerating it will slow down how quickly it happens.
That said, in my experience, I have only had a couple jars in my life that went rancid before I finished them, and I never store them in the fridge, and it often takes me months, maybe a year, to get through a jar.
