A riff on the classic Old Pal, made lighter and more approachable by red aperitivo liqueur replacing red bitter liqueur. Don't skip the spray of orange...
Agreed, I was wavering over adding a dash of angostura, but left well alone in the end and added an extra zesty spray instead. I think vermouth di Torino and high abv rye are key here for those of us who are used to and appreciate a heavy duty Manhattan etc.
