To make the cucumber juice, cut a whole cucumber into chunks and blend with a splash of water.
Pour the cucumber puree into a sieve and set aside the juice. Discard of the remaining solids.
Muddle the cucumber juice, blackberries and mint in a cocktail shaker until the berries break down.
Add the vodka (if using), lime juice, sugar syrup and a handful of ice. Shake for 30 seconds. Strain the mixture and pour into highball glasses with ice. Top with soda water.
Garnish with additional lime, mint and blackberry if you’d like.
A delicious cocktail idea for the weekend ahead! Our gorgeous Gin and Grapefruit Cocktail thoughtfully combines the tart flavour of grapefruit juice with the floral undertones of gin. Perfection!
