Soak your tiger nuts in a glass bowl or dish covered with cold water for up to 12 hours (or overnight). Make sure your tiger nuts are fully submerged.
Drain and rinse the soaked tiger nuts in a strainer and transfer them into your blender or food processor.
Add 5 cups of water, as well as a pinch of sea salt and vanilla if desired.
Blend in a high-speed blender for 1 to 2 minutes, or until the water has turned into a creamy white consistency.
Top a large glass bowl or measuring dish with a large strainer.
Line the strainer with roughly 4 layers of cheesecloth.
Pour out everything from your blender or food processor, making sure that none of the tiger nut pulp gets through. Using your hand, push down on the tiger nut pulp to get as much of the liquid out as possible.
Then fold up the sides of your cheesecloth so it forms a small sack, and holding your hand on the top, squeeze the pulp with your other hand (overtop of the strainer) to get the remaining liquid out.
Your milk is done! Pour your milk into glass mason jars and store in the fridge for up to one week.
