The mint notes were one of the first things I noticed on my first sip, but I am also impressed at how much bitterness just 1/4 oz of the Lucano imparts. Good balance overall. I use Cheritelli maraschino, which has a bit more maraschino flavor than Luxardo liqueur and plays well with a Luxardo cherry garnish. By way of contrast, Phil Ward (in the Death & Co. cocktail book) says "no garnish," but the Luxardo cherry works here, esp. with Cheritelli.
I’ll have to put this on my retry list, thanks Chris! I guess the bitterness of the amaro also amplifies the bitter elements in the carpano, even tho by itself the latter tastes so sweet (to my palate).
