Firefly Cooler

Description

Cucumber makes this elderflower cooler feel particularly fresh, and lemon gives its floral sweetness a clear edge. Vodka keeps the focus on those flavours and soda gives them a clean finish. Try it after an Elderflower Collins if the flowers appealed and you want a greener, quieter base.

Ingredients

  • 45 ml Vodka
  • 15 ml Elderflower Liqueur
  • 20 ml lemon juice
  • 3 pieces Cucumber slices
  • Approx. 80 ml Soda Water, to top
  • Ice
  • 1 piece Lemon twist

Instructions

  1. Gently press the cucumber slices in a shaker to release their fresh aroma without pulverising them.
  2. Add the vodka, elderflower liqueur and fresh lemon juice with ice, then shake briefly until cold.
  3. Fine strain into a highball over fresh ice and top with soda water.
  4. Stir gently and finish with a lemon twist.
