Blue Cucumber Elderflower Gin Fizz

Elderflower brings the sweetness, cucumber keeps it fresh, and a short pour of lemon stops the drink becoming too soft. The lemon also shifts the blue a little towards turquoise.

What you'll need

  • 45 ml dry gin
  • 15 ml elderflower liqueur or cordial
  • 15 ml fresh lemon juice
  • 30 ml cold water
  • 3 thin cucumber slices
  • 0.15 g blue spirulina
  • 60 ml chilled soda water
  • Ice
  • Cucumber ribbon, to finish

Elderflower cordial is usually sweeter than elderflower liqueur. If that is what you have, start with 10 ml and taste before adding more.

Make it

  1. 1Make the blue base. Stir the blue spirulina into the cold water until no specks remain.
  2. 2Gently press the cucumber slices in a shaker. Add the gin, elderflower, lemon juice, blue mixture, and ice.
  3. 3Shake briefly, then strain into an ice-filled highball glass.
  4. 4Top with chilled soda water, stir once, and garnish with a cucumber ribbon.

Keep the drink bright

Clear gin lets the colour show. Dark spirits, bitters and coloured syrups won't.

With 15 ml lemon, the drink will sit somewhere between blue and turquoise. Cut the lemon to 10 ml if colour matters more than sharpness.

Try it with

Alcohol-free

Replace the gin and elderflower liqueur with a botanical spirit and elderflower cordial.

Mint

Add four mint leaves with the cucumber and shake gently to keep the flavour fresh rather than bitter.

Blue spritz

Replace the soda with 75 ml dry sparkling wine and serve in a wine glass.

Making these for a cafe?

For ten drinks, batch everything except the soda:

  • 450 ml dry gin
  • 150 ml elderflower liqueur or cordial
  • 150 ml fresh lemon juice
  • 300 ml cold water
  • 20 thin cucumber slices
  • 1.5 g blue spirulina

Whisk the blue spirulina into the water first. Gently press the cucumber in the remaining ingredients, strain, combine with the blue mixture, and refrigerate.

Use 105 ml batch per drink and top with 60 ml soda. Make and use the batch on the same day; fresh cucumber loses its edge quickly.
