After the Brown Derby, I reached for Jeff Masson and Greg Boehm's Big Bartender's Book and found the Negroni Tredici. This Negroni variation was created by Toby Maloney at Chicago's Violet Hour in 2009; the 'tredici' part translates from Italian to 13, and this apparently reflects the 13 botanicals present in Cynar. Also, my instinct to reach for Tanqueray for Toby's drink given past recipes of his like the Thick As Thieves was correct, for I later found the recipe listed as such elsewhere.
