I used Carpano Dry vermouth to stay with the Italian theme, and the drink is just fantastic! The Amaretto is balanced nicely with the Campari. A spritz of orange to top it off. Amabile!
I disagree about too sweet (might the other reviewer have used sweet vermouth?)
Amaretto is a bit of a thug (see also Frangelico) overpowering drinks, and initial hit is all Amaretto, but the bitter Cynar came through.
Interesting, enjoyable, but not a Favourite.
"A bit weird" says Mrs Jones.
On first dates, stick to Old Fashioned, Negroni or Tequila Espresso Martini.
