Soak the cashews for at least 3 hours but preferably over night. When ready to make the sauce, rinse the cashews thoroughly and drain.
In a blender or food processor, combine all of the ingredients and blend until creamy and smooth. It may take a few minutes of blending to get a nice smooth consistency.
If you want the sauce a bit thinner, simply add in a bit more almond milk or water 1 tablespoon at a time until it reaches your desired consistency.
