Lathe-Turned Almond Butter

Pure almond butter comes with the somewhat stilted admonition “Must stir product. Oil separation occurs naturally.” I’d just opened a new jar and was busily (and laboriously) stirring when I realized we have the technology:

I installed the chuck’s outside jaws to grab the jar lid.

About three hours at 50 rpm, the lathe’s slowest speed, did the trick. We now have the smoothest, creamiest, best-mixed almond butter ever.

In a month or so, I’ll chuck up an unopened jar to see how well it works without any manual intervention.

    My problem with nut butters other than peanut butter isn’t so much the lack of stirring as the “you want me to pay HOW much per kilo?!?” factor.

      Of course peanut butter also needs to be stirred if it’s pure; I didn’t mean to put that as an opposition. :-P

      Aye! It’s something of a luxury item around here; I traded a nasty peanut butter jones for a much smaller almond-butter-on-celery addiction.

    Maybe you can use this as leverage towards a second lathe, you know, one for “cleaner or more sanitary jobs” like this. You could even call it the “kitchen lathe” if it helps the justification ;-)

      A watchmaker’s lathe would fit neatly on the kitchen counter …

    What if you were to run it at higher speeds? Would it centrifuge the solids out?

      Spinning slightly faster than 50 rpm produced an obvious void down the middle of the jar, so you’re probably right: a jar with a solid almond cylinder around an oil-and-air core. Faster speeds would decorate the shop with almond butter and coat it with almond oil …

    I like it!

    How about ver 2.0: the Ed-o-matic Nut Butter Stirring Machine(TM), fabricated from 3D printed parts, using an Arduino to control a Mabuchi motor or maybe a small stepper…

    If I had the 3D skilz, I would try it myself. Am thinking of a Vee-shaped frame with spinning rollers. Kind of like one of those hot dog grilling machines that you see at the ballpark, except bent upwards into a Vee, with the nut butter jar cradled by the rollers. The Vee should accept jars of various diameters, which would be handy.

    The Arduino could have various spin menus: slow, fast, ramp up and down, intermittent, etc. Maybe have the option to turn in reverse for users in the Antipodes :-)

    Seems like fodder for at least a couple of columns :-)

      Micromark actually sells a small set of powered rollers to keep your model paints mixed, although without any fancy controls.

      You come very close to the heart of the thing … [grin]

    An appropriate use of technology!

    This might be a use for those 1970s-era rock tumblers that every yard sale seemed to feature a while back
