*Soak the cashews in water for at least 8 hours (or overnight) so they soften up and are easy to blend. To quick-soak cashews, pour boiling hot water over the cashews and soak for 1 hour uncovered. When the cashews are done soaking, drain the water and rinse the cashews thoroughly. (Note: if you do the quick soak, the ice cream will no longer be raw).
**Prep time does not include soaking the cashews (8 hours).
