Makes about 2 1/2 cups.
Soak cashews in a bowl of water overnight in the refrigerator to soften them up if you have time. If you're in a rush, though, you can skip the soaking and the cream will still turn out fine.
Drain cashews and rinse well. Place in a blender with cold water to cover by one inch and blend until perfectly smooth. If you're using a high-speed blender, you're all done. With a regular blender, you may need to strain the cream through cheesecloth to achieve perfect smoothness.
