1 c. sugar
6 c. cold water
6 Tbsp. sweetened condensed milk
Mix cold water and sugar very well and chill until ready to use. This step can be done ahead of time.
Wash limes thoroughly with soap. Cut the ends off the limes and then cut each lime into 8ths.
Place 1/2 of the limes in your blender. Add 1/2 of the sugar water, place the lid on your blender, and pulse 5 times.
Serve immediately over lots of ice. Enjoy!
