Soak almonds, macadamia nuts, date, and sea salt in 4 cups of purified water overnight. In the morning, drain the water, rinse, and toss ingredients in a high-powered blender with 4 cups of cold, filtered water, and vanilla. Blend until smooth.
Pour mixture through a hop back or 2 layers of cheese cloth to filter our solids. Milk will keep in the fridge for about a week. Enjoy!
