Is this the actual recipe circa 2019? Or is it a guestimate of it (e.g. likely altered rather than authentic?) I haven't tried it, but at first read it looks unbalanced (sweet) as an equal parts. The undated note above says that the menu listed rye, cardamaro, dry vermouth, chartreuse verte; and the 2023 menu (online) says "Rye, Amaro, Dry Vermouth, Chartreuse Verte." So the establishment might be varying the amaro used; but I do wonder if the original used green rather than yellow chartreuse.
