2 ounces high-proof rye whiskey (such as Rittenhouse bonded)
1 ounce Carpano Antica Formula Vermouth
1 barspoon Oloroso sherry
6 drops Bittermens Xocolatl Mole Bitters
1 cured cherry (or a maraschino cherry)
Directions
Make the cured cherries: In a saucepan set over medium heat, combine the bourbon, Maraschino liqueur and brown sugar. Cook until the sugar dissolves, stirring occasionally, then add the cherries. Cool to room temperature and transfer to an airtight container. Refrigerate for at least 2 hours and up to 4 weeks (the cherries get stronger over time).
Make the cocktail: Fill a mixing glass or cocktail shaker with ice. Add the whiskey, vermouth, sherry and bitters. Stir well to chill, then strain into a chilled cocktail glass. Garnish with the cured cherry and serve.
