- In a cocktail shaker filled three-quarters full with ice, combine the Scotch whisky, sweet vermouth and aromatic bitters.
- Shake vigorously.
- Strain into two lowball glasses. Garnish each glass with a maraschino cherry.
Prefer your cocktails on the dry side? Swap sweet vermouth for dry (or combine the two, as with a perfect Manhattan) and replace the cherry with a twist of lemon. Angostura, or even Peychaud’s bitters are traditional here, but consider orange bitters for a dash of complexity.
