Once the tiger nuts are soaked, put them in a blender (you can also use an immersion blender) with about 1 cup of water and blend until you get a coarse paste. (If you have questions, you can check the video link below:

Now that you have a paste, gradually add the rest of the water while blending to extract as much flavor as possible from the tiger nuts.

Add the sweetener and blend a little more to mix everything well.

Next, use a fine mesh strainer to remove all the tiger nut solids. For an even smoother drink, strain again through a cheesecloth or fine mesh sieve.

Finally, pour the horchata into a pitcher or bottle and refrigerate until very cold. You can also put it in the freezer for a short time to enjoy it slightly slushy.
