Shake all ingredients with ice: London dry gin 45 ml · Lychee liqueur 20 ml · Pink grapefruit juice 20 ml · Bianco vermouth 15 ml · Saline solution 1 dash (opt.)
Fine strain into the chilled glass
Express a grapefruit twist over the cocktail and use as garnish
Optionally, garnish with a lychee on a skewer
Tips
Squeeze the pink grapefruit fresh; its bitterness is what keeps the lychee liqueur from tasting too sweet.
If you use the saline, one dash is enough; it sharpens the fruit without making the drink taste salty.
