  • 8 cups water / 4 cups water if using sweetener
  • 3 cups granulated sugar you can substitute an artificial sweetener
  • 6 cups pineapple juice
  • 5 cups vodka
  • 1 cup fresh lemon juice from 4 large lemons
  • 2 cups fresh grapefruit juice from 2 large grapefruits
  • 4 cups Sprite / 7Up + extra for mixing before serving you can substitute Sprite/7Up Zero or sparkling water


  • In a large saucepan over a high heat, stir together the water and granulated sugar or artificial sweetener. Bring to a boil and then reduce the heat down to medium-low. Leave to bubble for 10 minutes, until the sugar/sweetener has completely dissolved.
  • Pour the simple syrup into 29-cup plastic freezer-safe container. Leave to cool to room temperature for around 30 minutes.
  • When the simple syrup has cooled, stir in the rest of the ingredients (pineapple juice, vodka, lemon juice, grapefruit juice and 4 cups of Sprite/7Up/sparkling water). Place the container in the freezer for at least 24 hours to set.
  • When you're ready to serve, use an ice cream scoop to scoop out enough of the lemon vodka slush to fill a glass and pour over extra Sprite/7Up until it reaches the rim. Mix the drink with a straw or spoon to make it slushy then serve immediately.


1 glass is 180 calories if you use zero-calorie artificial sweetener and zero-calorie Sprite/7Up/sparkling water.
