Horchata de Chufa

I have recently started making my own tigernut milk as a dairy free alternative (it is also gluten free and, despite the name, nut free as they are actually tubers). I really thought I was on to something and being very creative until a client told me she used to drink it all the time in the Valencian region of Spain, where it is a very popular drink called horchata de chufa, usually served with cinnamon over ice.
It is really creamy, delicious and so much better to make if you have a blender and the time (shop bought milk alternatives usually have unwanted added ingredients)
I usually soak 1 cup of tiger nuts in water overnight ready to make the milk in the morning
Discard the water that the tiger nuts have been soaking in
Add the tiger nuts to a high speed blender with 2-3 cups of filtered water (depending on how thick and creamy you like it) and blend well
Then strain the liquid through a nut milk bag over a bowl to separate the milk from the pulp*
You can add cinnamon, vanilla, natural sweetener to the milk (although it is naturally quite sweet)
Store in a bottle in the fridge and enjoy :)
*Either discard or compost the pulp - however I am currently searching for some good recipes that uses this pulp - watch this space
