And to kick it up one last notch, cook your own beans rather then use canned.
Oh, heck yeah. I do keep a can of chickpeas in the pantry, but that's only in case of emergency. Otherwise, I've been cooking them in the Instant Pot. Rinse the dry beans well, add the to the pot with the water, push the "beans" button, bump the time up to 35 minutes, and let the magic happen.
For hummus, I like to let the beans cool if I can manage it. The texture isn't right, otherwise. If I really can wait, I go ahead and let them cool overnight in the fridge.
I might just try to ferment some hummus, with salt, the old school method instead of using fermented juice drippinz.
I looked into that, but it's difficult (if not impossible) to get around using some sort of starter. Dried, uncooked beans right out of the bag don't readily ferment because the starch chains still are so long and complex. You can sprout the beans so that the enzymes start cleaving those chains into something that yeasts or bacteria can digest, but that takes days and some work. After changing the water over and over, you probably want some manner of starter, anyhow, since you've pretty much rinsed away any good bugs that were on the beans. Cooked beans certainly need a starter, since you've killed off the good bugs. Trying to ferment the prepared hummus (or even just pulverized beans and stuff) doesn't work too well, either, because you still don't have the good bugs in there. Sure, they will eventually come from the air, but just on the surface.
In the end, I have an abundance of homemade starter from all the homemade sauerkraut, so it seemed like the thing to do. It worked so well that I don't see a whole lot of reason to start back from zero in the future.
