1oz Sweet Vermouth
Add all liquids to a mixing glass. Add ice and stir. Strain into a chilled double Old Fashioned glass. Garnish with the orange twist.
Another famous classic, the Negroni has a refreshing bitter citrus taste that is craved all over the world. For this one, it may be best to avoid heavier vermouths, such as Carpano Antica, as they overpower the gin in equal parts. Dolin Rouge works great in a Negroni.
Not a lot of debate on this one as most agree that the Negroni was invented in 1919 by Count Camillo Negroni. At the Caffe Casoni in Florence, Negroni asked a bartender named Fosco Scarcelli, to make his favorite drink, The Americano, with gin instead of club soda and thus the Negroni was born. Prior to prohibition, Campari was not imported to the United States, which led to a new recipes using it coming from American bartenders who left to tend in Europe after the start of prohibition. One side effect of this is that the Negroni, invented prior to prohibition, did not reach American publications until some time after prohibition ended, while the drinks made with Campari such as the Boulevardier and Old Pal were published in the US prior to this time.
Flame the orange peal for a little variety. If you only have heavier vermouths or are into a little variety, change the ratios a bit by adding more gin and less vermouth. Some people make this drink more heavy gin flavored in general and use a 2:1:1 ratio. I typically prefer the equal parts version as to me the balance is perfect. Play around and see what you think. There are innumerable variations on this drink, the most well known of which is probably the Boulevardier (also my favorite drink), which trades the gin for bourbon. More variations to come.
