2.
Strain into a chilled coupe glass.
3.
Garnish with a marasca cherry.
Notes
Rather than rely on a single vermouth, you can use a blend of some high quality ones. Justin Lavenue, co-owner and operator of The Roosevelt Room in Austin, came up with this blend: combine 750 ml Cocchi Vermouth di Torino, 19 oz Punt e Mes, and 6 oz Carpano Antica Formula.
