Cocktail - The Negroni

Adapted from Gabrielle Hamilton and The Cocktail Codex by Alex Day, Nick Fauchald, and David Kaplan  

The Negroni

For one drink

1 ounce Plymouth Gin
1 ounce Sweet Vermouth*
1 ounce Campari
Garnish with a half wheel of orange

Shake or stir the ingredients together and either strain into an old fashioned glass over ice or go rogue and serve straight up. 

*Regarding sweet vermouth:

Gabrielle Hamilton uses Noilly Prat in America, Martini in Italy (because it's available everywhere), and Antica Carpano if she having more than one because it's softer and less bitter, which is actually the point of an appetite-stimulating pre-dinner aperitif. (She does not recommend Dolin.) The Cocktail Codex boys without hesitation recommend Antica Carpano. I usually use Martini.
