It is easiest to make a smooth nut milk in a high-speed blender but you can make it in batches in a standard blender.
1/2cupraw skin on almonds
pinchsea salt, optional
Rinse the nuts in a strainer, and then put into a container, large enough to hold them and water to cover by 2-3 inches.
Drain and add to blender container.
Add 2 cups water and the optional pinch of salt.
Blend until smooth.
Pour into a nut milk bag set over a bowl or large measuring cup and milk the nuts: squeeze the milk from the nut pulp, until no more liquid is left. Refrigerate the nut milk in a clean jar until needed.
