After reading the comments, reduced the lime by 10%. Was definitely on the dry side, most enjoyable though. Used the recommended substitution Cocchi Vermouth Amaro...And then my cat tipped it over. Deliberately! Agent of entropy. (That's why we call him Mewsifer.) I'm making another. All is forgiven.
Agree with the above. Needed some sweetness. Added some honey syrup, split Amaro base Averna and Nonino, and rhubarb bitters and it was quite enjoyable.
It was just a little unbalanced for me. I tend to like sour drinks but this was a tad heavy on the sour. I added just a teeny bit of grenadine (about 1/8 oz) and another 1/8 oz of allspice, and that was enough to balance it out for me.
