You can make a delicious, creamy non-dairy nut milk from raw cashews. They can be added directly to smoothies to make them creamier, or you can create this nut milk and use them in smoothies, on raw granola, or other dishes.
Cashews are quite soft and will blend well without soaking, but if you have problems digesting nuts you may want to pre-soak them for 6-12 hours and throw away the soak water before you proceed.
Blend cashews, water, salt and sweetener on high until creamy.
If you don't have a very powerful blender you might want to use soaked cashews and/or add only half the water to start, and when the cashews are well blended add the rest. If you have a powerful blender, like a Vita-mix it's easy, just add all the ingredients and blend.
Depending on what you want to use the cashew milk for it may be fine as-is, but you can also strain it through a fine sieve or nut milk bag or piece of muslin to remove the fiber. Be sure to save the nut fiber to use in cookies and other recipes.
Cashew milk can be substituted where I have used almond or other nut milks in most of the recipes here.
