*Soak the cashews in water for at least 8 hours (or overnight) so they soften up and are easy to blend. To quick-soak, pour boiling hot water over the cashews and soak for 1 hour. When the cashews are done soaking, drain the water and rinse the cashews thoroughly.
**Use vanilla extract that contains alcohol. Alcohol prevents big ice crystals from forming, resulting in a softer texture.
***Because the ice cream doesn't contain any emulsifiers or stabilizers, and is not technically churned, it gets harder and icier the longer it sits in the freezer. So, it's best consumed immediately or as soon as possible.
