Well, I played around a bit with the Chef Watson site (still no account required). It gave a big thumbs-up to some of my favorite flavor combinations, but then we came to bit of an impasse.
I put in Gin, Campari, Sweet Vermouth.
Chef Watson said: zero synergy.
Interesting. So I've been liking the wrong drink all these years. I asked Watson for suggestions; he ditched the gin and substituted salt cod.
Who's coming over for cocktails?
