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.
