Add all of the ingredients to a blender (it should be pretty powerful) and blend on high speed until very smooth.
1 ½ cups shredded unsweetened coconut, 3 cups water, ⅛ teaspoon sea salt, 2 soft dates, ½ teaspoon vanilla extract
Strain the milk through a couple layers of cheesecloth or a nut milk bag. Transfer the milk to a tightly sealed glass container and either compost or use the pulp in another recipe.
Shake the milk well before each use. Separation is normal.
Notes
This makes a little bit less than 4 cups (1 litre) of coconut milk.
