Soak the cashews: add cashew to a glass jar and cover with 2 cups water. Store in the refrigerator overnight and up to 48 hours.
Drain and rinse cashews.
Add cashews, 1¾ cup water, honey, and salt to the blender (add any add-ons at this time as well). Blend on high for 2 minutes or until smooth and creamy.
Add additional water to adjust thickness if desired.
