This recipe has nothing in it but Ginger and water. I used enough water to cover the Ginger in the blender. You can add more if you like, but this amount seems to be enough. We add this to our smoothies to give them a bit of zing. You will need a high speed blender like a Vita-Mix for this to break up the Ginger. Use the juice sparingly, it is quite strong. Remember to shake the jar well before using, the ginger does tend to accumulate on the bottom of the jar. You may even have to stir it as it can stick down there.
