A bittersweet Negroni-like aperitivo or digestivo with pleasing, subtle, rich cherry notes. This cocktail runs so much better on high-octane Navy strength...
Many thanks, Chris. I've added this, and all I can find on the history to what I already had. Hopefully, a French speaker will have more luck than me searching online archives of 1928 Parian newspapers.
Have tried it, I've restored the recipe to how it was originally intended: 6 equal parts. (Previously i had a third less of the last two ingredients - the vermouths.)
