Fabulous story. of course I want to try it, but sadly, don't have the materials or the patience. Said as I was enjoying a pretty bog-standard Negroni with Campari, Tanqueray, and Cinzano in semi-equal parts, imagining the fancier one. About to mix another.
Maybe I was trying for one of the other ones and was missing an ingredient and liked it anyway. However, I only have one more to go, since my local shop doesn't have any chartreuse - green or yellow. Is there any reasonable substitute? Those monks seem to be hoarding.
I make a cocktail I named "Who knows" which is 1 shot of green chartreuse, 1 shot of lillet, 1/2 shot of Cointreau, 1/2 lime, shaken with ice. I couldn't find it, but I'm sure I'm not the first, and I'm sure it has a name.
