Butter-wouldn’t-melt Sophie Dahl adds olive brine to this classic combo of vodka and vermouth to dirty up her Martini.
Pour the vodka, dry vermouth and olive brine into a cocktail shaker with a handful of ice and shake well.
Rub the rim of a martini glass with the wedge of lemon.
Strain the contents of the cocktail shaker into the glass and add the olive.
