I just made this drink, using the Amer Picon substitute from the Truffles on the Rocks YouTube channel (which has worked for me in the Brooklyn), and I enjoyed it. I would definitely make it again and serve it to guests.

This is a Sweet Martini with Amer Picon and Angostura orange bitters as a bittering agent, and it's an improvement on the traditional Sweet Martini. (Angostura orange bitters are gentian-based, so I wouldn't use a substitute where this brand is specified, even though I usually use Regan's in Martinis. The Truffles on the Rocks Amer Picon substitute specifies Angostura orange bitters.)
