Absolutely my favorite rendition so far. The maraschino shines in the background. I've tried this with many rums: Appleton signature is very good. I also like the richness of Hamilton 86 in this.
I made this drink exactly and it was great (my rating was based on that).
I then remade the drink with Granada-Vallet (a bitter pomegranate liqueur from Mexico) instead of Campari, and it was out of this world. It rounds out the negroni with flavors of gentian, fresh jalapeƱo and lime zest.
Highly recommend the variation if you can get your hands on a bottle.
Went through this one twice, once with the original and once with 20 ml campari. Really liked the second version, maybe because my passionfruit syrup was a bit sweeter? Either way, great drink.
