A fabulously fizzy, super delicious and nutritious citrus drink with fresh lemon, lime and pink grapefruit.
Juice the citrus into a medium bowl - my favourite tool is a simple wooden reamer. Sieve the juice into another bowl, then pour into an ice cube tray and freeze.
Mix 2-3 juice cubes with a glass of sparkling water and enjoy!
Makes about one medium-sized ice cube tray.
