Short and punchy and Manhattan-like. Best appreciated as an after-dinner digestivo or late-night sipper. Thanks to feedback and much refining, I'm happy...
I've not made this cocktail, but have a substantial page of saved substitutions & will at least try this: Mix equal parts of Averna, Suze, & Cointreau, then add a few dashes of Angostura orange bitters to replicate the profile of Amer Picon.
