A perfect Manhattan with bittersweet liqueur rather than aromatic bitters and a balancing dash of sweet maraschino liqueur.
If you can't obtain Picon...
So tried making a Amer Picon substititute again that I could just batch. Equal parts orange bitters, Cointreau, Aperol, and Nonino Amaro. Will still work on sourcing some Amer Picon though.
