Quinine Sour Recipe

When craving a Gin & Tonic but wanting something new to try, one of our most popular off-menu cocktails, The Quinine Sour, is the perfect contender putting a sour spin on the classic Serve. The best bit about this is that it can easily be recreated at home, simply follow the recipe below.

Ingredients and Barware:

Champagne coupe, to serve

3 thin slices of Chopped Ginger

3 fresh Curry Leaves (and 1 extra, to garnish)

50ml London Dry Gin

25ml Lemon Juice

1 tablespoon Simple Syrup

3 dashes Tonic Bitters (we use The Bitter Truth Tonic Bitters)

25ml (1 part) Egg White (or Aquafaba)

Whole Ice


  1. Put the champagne coupe in the fridge or freezer a little in advance to chill it. 
  2. Take the three finely-sliced pieces of chopped ginger and three fresh curry leaves and muddle them together inside your cocktail shaker. Add the gin, fresh lemon juice, sugar syrup and tonic bitters. 
  3. Separate the egg, and add the white to your cocktail shaker.
  4. Close the cocktail shaker and shake vigorously for 10 seconds without any ice — this will help create a good foam.
  5. Open the shaker and completely fill it with ice. Give it a good hard shake for another 20 seconds to chill the cocktail.
  6. Strain the cocktail into your chilled glass and garnish with a curry leaf resting on the foam.
