Very tasty with Gosling's and the right amount of maraschino. Used Ramazotti for the Amaro since it was on hand and surprisingly it's a little lost. Want to try again with some other subs (think Abano might be a good choice).
As a huge fan of rum, loved this. Used Hamilton Pot Stilled Black Jamaican at 90+proof. Cocktail starts off with a hit of Jamaican rum funk followed by the spices of the Amaro and angostura. Ends with hints of pepper and cherries. Found the cocktail alive with a burst of flavours and hints of Caribbean mystic. Does benefit from a very long stir. Allow to breathe as the initial sharp flavours do mellow as it breathes.
As the commenter below says, this is an intense, dark and brooding cocktail, but I did enjoy it. The second time I made it, I used Peychaud's instead of Angostura, and it added nice, subtle zing to the mix.
