Soak macadamia nuts in cool or room temperature water for 1-2 hours. Then rinse and drain.
Add nuts, water, salt, and any additional add-ins (optional) to a high-speed blender. Top with lid and cover with a towel to ensure it doesn't splash. Blend for about 2 minutes or until the mixture seems well combined.
Scoop out a small sample with a spoon to test flavor/sweetness. Add more dates, salt, or vanilla as needed.
Pour the mixture over a large mixing bowl or pitcher covered with a nut milk bag, a very thin towel, or a clean T-shirt. In my experience, it benefits from a single strain either through a very thin towel or nut milk bag. Save pulp for baked goods or to add to oatmeal, smoothies, or energy bites.
Transfer to a sealed container and refrigerate. Will keep in the refrigerator up to 5 days (sometimes more). Enjoy cold or hot and shake well before use (it tends to separate in the refrigerator). Can be used in smoothies, with granola, for golden milk or matcha lattes, or baked goods!
*Nutrition information is a rough estimate calculated with lesser amount of water (excess macadamia pulp nutrition was subtracted from total) and no additional add-ins.
