In a large bowl, mix together the sugar and zest. Use your hands to really run the lemon zest into the sugar, to release the essential oils of the lemon and really fragrance the sugar.
Place the sugar into a large container with a tight lid.
Add 1 1/2 cups of hot water and shake (with the lid sealed) until the sugar dissolves.
Stir in 1 1/2 cups of fresh squeezed lemon juice (about 8 lemons worth).
Place this jar into the fridge until ready to use.
Notes
*To Serve 1 Glass*
In a large glass, mix 1/3 cup of the lemon syrup with 3/4 cup cold water.
