I've been really enjoying a cocktail I came up with when experimenting with Cynar. Basically, I took my standard manhattan (2 oz Rittenhouse rye, 1 oz Carpano, angostura bitters, Luxardo cherry) and swapped in Cynar for the Carpano. (I originally did half and half, but I liked the emphasis on the Cynar.) Then I realized that Cynar reminds me a lot of a darker, richer Campari and Campari goes great with grapefruit, so I subbed in grapefruit bitters for the Angostura, which really brightened up the drink. Finally, the cherry seemed inappropriate so I ended up using an orange zest twist. It's delicious - kind of like a boulevardier, but darker and stronger.
Anyone know if there's a name for this? I'm assuming others have probably followed the same logic and arrived at a similar drink.
