top with Sparkling Mineral Water about 2 ounces each
basil leaves and flower sprigs for garnish
Instructions
In a cocktail shaker, combine 1/2 of the grapefruit juice and the basil leaves and muddle to release the basil oils into the liquid. Add remaining grapefruit juice, aromatic bitters, and ice. Shake vigourously.
Using a cocktail strainer, strain mixture evenly into two goblets, discarding what remains in the cocktail shaker.
Add 1.5 ounces of ginger ale into each goblet and then top with sparkling mineral water until glass is full, about 2 ounces.
