It is perfectly balanced in my opinion, thanks to the passion fruit. I don’t see how anyone who is open to Campari would be alienated by this one. Another for the regular rotation.
This truly benefits from a couple or few dashes of chocolate bitters in my opinion. Provides a needed depth and balance (for me, anyway). Also wondering if orange bitters might be an interesting variation, like a chocolate orange. Definitely in my dessert cocktail rotation now.
