Bartending Question:

I'd use 1 part Tanqueray - because I like to use a premium gin, but nothing as distinct as Hendricks or Tanq 10 where you're just going to lose the flavour when you add the Campari - I'd use 1 part Campari - Aperol is an ok substitute, but it's just not the real thing - and then I'd use 1 part Cinzano Rosso - I think it has a bolder flavour than Martini Rosso, so it'll stand out better in a cocktail. I'd put all that into a double rocks glass, easy ice, and then with a cocktail stirrer give it a good stir for about 15 seconds, so the customer gets the well mixed, well balanced cocktail they expect when they order a Negroni. Then I'd finish it off with an orange twist.
