Making nut milk in a blender is actually quite simple. First, soak nuts overnight in water. This step helps soften the nuts. The next day, add the soaked nuts to your blender with clean water. A good ratio to start with is one cup of nuts to four to five cups of water. You can also add flavors and sweeteners like cinnamon, maple syrup, or vanilla extract to the blender. Blend for one to two minutes until creamy and smooth. You’ll notice the liquid and solid pulp will separate pretty quickly after blending, so to make extra smooth nut milk, strain out the liquid from the pulp using a nut milk bag.
