Whilst the ultimate test of a good bartender is the Martini, probably the second biggest challenge is the Negroni as it calls for absolute control of the proportions of the Gin, Campari and Rosso Vermouth that make up its constituents.
The Negroni was created (or so the story goes) in the Caffé Casoni in Florence in 1919 for Count Camillo Negroni who was getting bored with his usual cocktail, the Americano. Either he, or his barman, Fosco Scarselli, ditched the soda water and replaced it with gin. Sadly the Caffé Casoni is no longer there and the site is now Caffé Giacosa owned by and attached to the Milan fashion shop of Roberto Cavalli.

The Negroni can be thought of, therefore, as a supercharged Americano. It needs to be scrupulously made from equal parts gin, Campari and rosso vermouth; a few centilitres out for each ingedient unbalances the drink.
Jessica demonstrates the stemmed glass approach...
How do you want it?
Other people mess around with the ingredients: replacing gin with vodka (Negroski), using spumante instead of gin (Negroni Sbagliato), replacing the red vermouth with dry vermouth, fiddling with the proportions such as 3-2-1 Gin, Campari and Vermouth. However, none of these are real Negronis and Triple P wouldn't drink any of them.
So long boys...
