This one, a very tasty Manhattan variation, came from The Old Waldorf-Astoria Bar Book. For best results, use a high-quality, spicy sweet vermouth like Carpano’s Punt E Mes or Antica Formula, and Regans’ Orange Bitters No. 6.

The Marconi Wireless Cocktail

2 ounces applejack (or straight apple brandy, preferably).
1 ounce sweet vermouth.
2 dashes orange bitters.

Stir with ice for no less than 30 seconds.
Strain into a cocktail glass, and garnish with a cherry.

Yum.
