One of the more prominent stories surrounding the origin of the Negroni is as follows. In the early 1920's Count Camillo Negroni, looking to get a little more kick out of his Americanos, ordered them with the addition of Gin.
He ordered this libation so frequently at bars and cafes in and around Florence (Italy) that bartenders eventually named the drink after him.
30ml Hayman's London Dry Gin
30ml Dolin Rouge Vermouth
In an ice filled mixing glass (Martini pitcher), add Gin, Vermouth and Campari. Stir until well blended. Strain into a chilled Cocktail Glass or as I prefer into an old fashioned glass over ice.
Garnish with a burnt orange twist.

SHAKE AND STRAIN
Using a Hawthorn strainer (or knife) this technique prevents the ice going into the glass. Straining protects the cocktail ensuring melted ice wont dilute the flavour and mixture.
