Unsalted natural peanut butter is just roasted peanuts. Salted natural peanut butter is just peanuts and salt. The oil is just from the peanuts, not added.

No mix peanut butter is the same but with palm oil and usually whichever sweeteners are cheapest. Palm oil hardens at room temperature and keeps the peanut oil from separating.

The peanut butter I buy is 99% peanuts and 1% salt.

Sounds like you've never been to a hippy store. They sometimes have machines that you pour the peanuts into and then you have some peanut butter. You can also have cashew butter, etc.

They do! But the oil separates and you have to stir it first. And it needs to be refrigerated after opening.

Convenience, whether it's for the producer or consumer, got us again.

I make my own peanut butter because I like it extra roasty. It's like 500g peanuts, a half teaspoon of salt.

they can, and some brands only make it like that, but others want peanut butter that doesn't shift and so add other oils

Yes but it will separate and you need to stir it up to get all the layers mixed together

it’s literally what pb is.
