- A Canning or Preserving jar with a tight lid (big or small- your choice, you can even use an old pickle jar)
- Fresh Whole (Preferably Organic) Lemons. There isn't a hard fast number for them, because the number depends on how big your jar is. But I would get more than you think you need- you have to have enough for juice too.
- 1 or 2 cups of Pickling, Kosher, or Sea Salt.
