  • For a Key Lime La Croix mocktail, simply omit the vodka.
  • If you prefer your cocktails a bit sweeter, add in a hint of simple syrup to each glass.
  • For a large batch, simply combine all into a pitcher and then serve.
  • If you’re unable to find key lime juice, regular lime juice can be used instead.
