Soak the cashews over night or at least for 2 Hours. If you forgot to soak your cashews but are short on time you could also boil them for 20 minutes.
Add the soaked cashews with the rest of the ingredients into a blender and blend until smooth. If the sauce is too thick you can add water until it becomes the consistency you desire.
Then add the sauce into a little pot and heat it up while stirring.
Finally add the sauce over cooked pasta. Enjoy!
