Grind/blend the tiger nuts in water. Pour all of it into a cotton bag (like people use for Greek yogurt) or cheese cloth over a bowl, then squeeze the hell out of it until all the tiger nut milk is out. I still use a cotton bag, but cranking it with a press is WAY easier, faster, and more effective.
Its also apparently good for your gut microbiome, which most people now seem to need help with.

(Although this seems to be the Spanish version using Tiger nuts instead of rice.)
It’s not hard to make and the tiger nards version is really good. We bought a fruit press so I can make it even more easily.
What’s the non fruit press way?
