Zest your lemon
Then slice up the remaining part of the lemon, discarding the ends
Blend everything together until smooth
Pour into silicone tray and freeze for 1 hour-2 until hard (optional for thick blizzard style. Otherwise it will be thinner smoothie like)
Place those in the blender and blend. You may need to scrape the sides in between blends. Can add a splash of coconut milk to help break it up if necessary
Pour into 2-3 glasses and enjoy!
