Three measures of Gordon’s, one of vodka, half a measure of Kina Lillet.
The Negroni is the first cocktail mentioned in the book but the Vesper is the most famous. Some readers took me to task for this, pointing out that it is in this very book that the most famous of Bond cocktails, the Vesper Martini (named after the novel’s lead female character, Vesper Lynd), was created. Last Friday, in writing about the Negroni cocktail, I mentioned that its precursor, the Americano, is what James Bond first orders in Casino Royale.
