A refreshing spring/summer cooler – light on the alcohol, but made fragrant by the elderflower/grapefruit combo.

In a cocktail shaker 1/3 filled with ice, shake together 30ml gin, 50ml St Germain (or other elderflower liqueur, a dash of Angostura bitters and 200ml pink grapefruit juice.

Strain into chilled cocktail glasses. Serves 3.
