Luca Picchi of Rivoire in Florence, Italy, sticks to tradition when making this superlative cocktail. The classic was first created for Count Camillo Negroni in 1919 at Florence's Café Casoni. The bartender who supposedly invented the drink, a man named Fosco Scarselli, later sent a letter to the count advising him not to imbibe more than 20 of the cocktails per day.
