How to make the perfect Old Pal.
30ml Dry vermouth
Stir over ice, strain into a chilled cocktail glass, and garnish with a lemon twist.
Serving suggestion: Serve straight up because the intriguing flavour shifts that come from serving on the rocks play out less well with dry vermouth. The Old Pal is best as a dry aperitif, so try nudging things slightly to favour the rye and vermouth.
