Soak shelled pistachios in water for at least 6 hours (overnight is fine)
Drain and rinse well
Place soaked pistachios in a blender with water
Blend until smooth
Add remaining ingredients and blend until well combined
Pour contents of blender through a nut milk bag into a wide mouthed jug/bowl
Squeeze bag well, ensuring all milk is drained
Store milk in an airtight container in the fridge for up to 5 days (if it lasts that long!)
Use in place of any milk in cereals, baked goods, smoothies or warm drinks such as hot chocolate
Remaining nut pulp can also be stored in an airtight container in the fridge for use in smoothies, raw treats or baking. Note however that this pulp/meal is a wet product.
Notes
When using the milk from the fridge, you may need to shake it as the water can separate.
Use of a high powered blender and nut milk bag are unavoidable and make all the difference in this recipe.
