Cover tigernuts with water and soak for 24 hours in the refrigerator (they may ferment if left sitting on the counter).
Drain and rinse the tigeruts.
Add the tigernuts and 4 cups of water to a high speed blender. Blend for about a minute until creamy.
Strain through a nut bag and place into a glass bottle. Refrigerate.
This milk needs to be used within about 3 days. If you are not going to use it within that time, you can freeze it for later use.
This milk is so super creamy and delicious that you will want to drink it by the glass!
