Add seeds to blender along with the 3 cups of water. Blend for 1-2 minutes on high until smooth. Pour into a strainer or nut milk bag. Squeeze gently until all the liquid is extracted. Pour the filtered milk back into the blender with all other ingredients and blend for 1 minute. The sesame milk tastes best cold; refrigerate for 30 mins. You will need to stir before drinking as the ingredients will settle to the bottom.
