This is a perfect evening sipper. Bourbon forward with a softening from the vermouth and Chambord. Well balanced and not overly sweet. On my favourites and would definitely have again.
I was out of my Angels Envy Bourbon, so I used Angels Envy Rye and added some Fee Brothers Whiskey Barrel Bitters alongside the Angostura Bitters. Will definitely be making this again, but 100% agree with Peter that it is a after dinner/dessert drink.
In the Manhattan vein but fruitier and less vapory, the Chambord adds such a nice change of pace, and plopping in a few fresh home-made Maraschinos went a long way. Would be a nice after dinner and/or dessert drink.
