I want to make nut butter from soaked cashews or soaked pepitas. I am wondering what type of machine will get the smoothest product?

I am currently using a food processor which is great for cashews but I'm wondering if I can do better. Other possibilities include a blender, nut butter machine, and some type of grinder (perhaps a wet grinder?).

  • Doesn’t soak the nuts just mean you get water in the butter, reducing its keeping properties?

  • If you soak it, the the fat will emulsify an you get cashew "milk" not butter. Dec 23, 2019 at 18:19
  • Ok, this is true. But I am fine with a bit of water in the product. And I'm guessing that the answer for which machine to use is the same. Dec 23, 2019 at 23:17

Any machine that can reduce the nuts to very fine granules should do the job.

Wet grinders given there’s enough liquid/fat content in the nuts should do the best job. However that might not always be the case. Special high powered blenders (such a blendtec) with a purpose designed jar (like a twister jar) would generally provide more reliable results.


To make smooth nut butters you need a melanger or a wet grinder. If you have a boatload of cash to spend, this will do the job nicely. Otherwise, you can get in the game for under $200 US with this wet grinder. You will never get a smooth product with a food processor, or even a high speed blender. There will always be some perceptible grit with those tools.


I haven't used grinders (and I don't know which home grinders are suitable), but a good machine for this is a masticating juicer. Even though it is called a "juicer", it only separates the juice from the pulp in a late step, by pressing the whole mousse through a fine screen. The models sold nowadays come with a part made of smooth plastic which replaces the screen, and all the "chewed" stuff falls out through the juice hole instead of being separated.

Because of the squishing action of the cylinders, it gives you a smooth result where all bladed products end up with small pieces.
