Drinking our walnuts has been a refreshing pleasure, and a simple way to take advantage of their antioxidant and anti-inflammatory benefits (they are the only nut with a significant amount of omega 3s!). It’s rich, creamy, and flavored like the pure essence of walnuts. You can drink it straight up, add to smoothies or pour over granola, but my personal favorite application is to use it as a base for hot cocoa. So unique and delicious!
This was my first time making nut milk, and although I’m familiar with the basic soak/blend/strain procedure, I had to wonder what kind of chemistry makes this simple process work so well. After consulting my go-to resource on these matters, I learned that it’s all about the way that nuts store their oils. The healthy fats found in nuts are dispersed in little globules called oil bodies, whose surfaces are covered with proteins and phospholipids to prevent them from merging together. When dry nuts are blended, their oil body surfaces are torn up and the oils pool together – think nut butter. But when soaked nuts are blended, the oil bodies are able to remain intact, and disperse as fat droplets into the water, along with proteins, sugars, and salts – just like milk!
If my geeking out is making your eyes glaze over, whoops. We can move on to the procedure now, which I assure you is really simple…
And voila! I just add a pinch of salt to make the flavor sing, but you can also doctor it up with vanilla or other additions.
Apparently the leftover pulp can be dehydrated to make walnut flour, but since my dehydrator is sadly exiled on the opposite coast in my parents’ storage closet, I haven’t tried it out yet. If you’re already a nut milk DIY-er, I would love to hear your favorite suggestions for nut pulp usage!
I also wish that I knew more about how the nutrients distribute into the milk and pulp fractions… The California Walnut Board provides nutrition information for their recipe, but it’s not clear how it was determined. Aside from that, my research has come up dry. Any insights, intrepid readers?
