Choosing a peanut butter used to be as simple as creamy or crunchy, Jif or Skippy. You either liked a little texture in your peanut butter, or you wanted a smooth spread you could swirl over a piece of bread in thick waves. But whatever jar you took to the checkout counter was going to have a familiar taste: salty, sweet, sticky, and with a uniform consistency.

That was how shopping for peanut butter used to be. Then natural peanut butters came on the market, and everything blew up! Well, not really, but they sure did shake some people’s assumptions of what peanut butter should taste like.

Whether you’re ready to ditch Jif and try Justin’s (and we have thoughts on that!), or want to know what all the fuss is about, here’s the low-down on natural peanut butter.

WHAT IS NATURAL PEANUT BUTTER?

Natural peanut butter contains just peanuts and salt (and sometimes not even the salt). No fully hydrogenated vegetable oils, no sugar – both of which are found in conventional peanut butters.

WHY DO SOME PEOPLE PREFER NATURAL PEANUT BUTTER?

What causes someone to skip out on the Skippy and ride a train in the natural lane? The same reason anyone chooses the more “natural” alternative, be it with food, household, or personal products: fewer ingredients, less processing, and overall a product that is closer to its original source – which in this case is, of course, peanuts.

Because of this, natural peanut butters may have a grittier texture, even the ones labeled creamy, but with a definite peanut-forward flavor!

WHY DOES NATURAL PEANUT BUTTER SEPARATE? 

One of the biggest differences between conventional and natural peanut butters comes down to stirring: Natural peanut butter requires a good stir when you open it, while conventional peanut butter does not. Why is that?

As mentioned above, conventional peanut butters are made with fully hydrogenated vegetable oils, which help stabilize the peanut butter, prevent it from separating due to time or temperature, and give it that smooth, homogenous, creamy texture. There’s no stirring required; just open the jar, dig in with a spoon, and get on with that snack of yours.

But natural peanut butter does not contain any fully hydrogenated oils, and is therefore not homogenized, so the peanut oil will separate from the solids, probably while it’s sitting in a shipping container headed to your local grocery store. So unless you enjoy a nice spoonful of peanut oil with your strawberry jam, you’ll need to stir natural peanut butter and mix it all up again before you eat it.

Fun Fact: Conventional peanut butters used to be made with partially hydrogenated vegetable oils, which contained trans fat. But in 2015 the FDA ruled that all peanut butter should be made with fully hydrogenated vegetable oil, which does not contain trans fat. Now all major peanut butter brands in the US, conventional and natural, contain zero grams of trans fat per serving.

WHAT ABOUT PALM OIL?

According to the FDA, any product labeled peanut butter must be made with at least 90% peanuts, with the other 10% going to “seasoning and stabilizing ingredients” like salt, sugar, and hydrogenated vegetable oils, if desired. If any so-called peanut butter contains less than 90% peanuts, or any oils or ingredients other than those listed above, it can’t be called peanut butter. It’s instead a peanut butter spread. (Semantics, man!)

And so we come to palm oil.

Some natural peanut butters contain palm oil, or palm fruit oil, in their list of ingredients. Palm oil is tropical fruit oil derived from palm trees, and because it’s semi-solid at room temperature, it’s added to natural peanut butter to stabilize it, reduce oil separation, and keep the butter uniform and emulsified. In other words, palm oil is basically the way to get a no-stir natural peanut butter.

But since palm oil is not an FDA-approved ingredient for peanut butter, peanut butter made with palm oil is technically not peanut butter, but peanut butter spread – just, so you know.

Additionally, I can’t talk about palm oil without talking about the reasons some people think it shouldn’t be in natural peanut butter (er, spread) at all, or really in any products, namely due to serious environmental concerns. Some natural peanut butter manufacturers, like Justin’s, who use palm oil in their products, are members of the RSPO (Roundtable of Sustainable Palm), which “encourages sustainable growing practices and human rights initiatives at the farm level, while promoting education about the cultivation and use of certified sustainable palm oil.”

If that doesn’t assuage your concerns, then it’s probably best to avoid palm oil altogether and go for the jar with just peanuts and salt as the listed ingredients (which you will then have to stir).

WHAT IS THE BEST WAY TO STIR NATURAL PEANUT BUTTER?

Why am I even asking this question, you may wonder? Isn’t stirring … stirring? Like, taking a spoon and moving it in a circular direction until the thing in question has come together?

Yes, well done on your stirring knowledge!

The issue with stirring natural peanut butter, however, is this: It can be kind of a mess. No matter how careful you are, you’re likely to slosh the oil out of the jar and onto your fingers and the countertop. It’s also time-consuming to get it all mixed together. But there are a few tips and tricks out there for minimizing the mess:

  1. Store the peanut butter jar upside down. The idea here is that by storing the jar upside down, the oil travels back up inside the solids and mixes itself. After letting it sit this way for a few days, shake it for 20-30 seconds before opening.
  2. Mix the peanut butter with an immersion blender: Forget hand mixing! Let the immersion blender do the work for you.
  3. Blend the peanut butter in a blender or food processor: Same process as the immersion blender, just scaled up.
  4. Use one of these: Made to fit on top of peanut butter jars, it’s got a built-in handle for stirring.

I tried all these different methods, and ended up liking the upside-down method best!

WILL THE PEANUT BUTTER RE-SEPARATE? HOW SHOULD I STORE IT?

If you stir or mix the peanut butter really well right after opening, then store it in the refrigerator, it should stay well-mixed and won’t require any re-stirring.

HOW LONG DOES NATURAL PEANUT BUTTER LAST?

Until you decide that one batch of these Chocolate Chip Peanut Butter Energy Bars wasn’t enough and you have to make two more batches immediately.

Oh wait, you mean like last in the jar, without eating it? Sorry, my brain totally cannot compute that concept. But if forced, I’ll say what the National Peanut Board says: 6 months in the refrigerator.

CAN I SUBSTITUTE NATURAL PEANUT BUTTER FOR REGULAR IN RECIPES?

Like many things, it all depends on what you’re making. For most instances other than baking, substituting natural peanut butter for conventional should be absolutely fine.

Baking with natural peanut butter can be a little more problematic, however, since the looser, thinner consistency of natural peanut butter may make baked goods (peanut butter cookies, for example) spread in the oven, or not bake properly.

One way to counter this is to chill the dough prior to baking to give the peanut butter a chance to firm up, or reduce the baking time so the cookies don’t get too crisp.

You may also need to add more salt or sugar to the recipe itself if you’re using unsalted natural peanut butter. As we now know, natural peanut butter doesn’t contain any added sugars, so you would be missing that sweetness unless you add more sugar elsewhere.

    I buy the just-ground honey-roasted pb from the Whole Foods bulk section, and it never separates.

    One needs to be Careful with the term “Natural” – if you look at the label of Jif Natural Creamy Peanut Butter you will see -Made From Peanuts, Sugar, Palm Oil, Contains 2% Or Less Of: Salt, Molasses. Others are this way as well since the term itself is not regulated. I always check the ingredients label rather than rely on the term Natural. We prefer salted here and while my husband laughed when I bought one of the mixers linked to above, we are very pleased at how much easier and less messy it makes mixing. Just make sure to get the right size for the peanut butter you usually buy (different size jars and lids) We store in the refrigerator after mixing. I use in baking as is but is can change results somewhat but not really a problem, we prefer the reduced sweetness.

    I make my own peanut butter and it doesn’t separate. However, the sesame seed one which is store bought always separates, so I keep the jar upside down.

    Refrigerating natural peanut butter keeps it from separating. That is my go-to method. You’ll need to let it sit out for 10 min or a 30sec defrost in the microwave to make it spreadable, but that’s a small price to pay.
