Ingredients

4 cups organic cane sugar
4 cups water
Zest of a couple of lemons
3 cups fresh lemon juice

Directions

Simple syrup is simple - it’s one part sugar to one part water.
Cook sugar, water and lemon zest over medium-high heat until sugar is dissolved and water boils.
Remove and let cool. Add lemon juice and store in refrigerator until the PARTY!

I tried about 1/2 cup of syrup with the liter bottle that comes with the Sodastream and it seemed to do the trick - YUM.
