Soak the cashews in water overnight or at least for 6-8 hours. You can also boil the cashews in water for 30 minutes in case you have forgotten to soak them.
Once the cashews are ready, add all the ingredients in a blender and blend until a smooth sauce is formed.
If the obtained sauce is still too thick for your taste, you can add the almond milk to dilute it further. But be sure to not dilute the sauce too much because very watery sauce would not coat the pasta very well.
You can add this sauce to the pasta and serve.
You can also refrigerate this sauce for up to a week for later use.
