|Old Tom Gin||4.5cl 1.5oz|
|Sweet vermouth||4.5cl 1.5oz|
|Angostura bitters||Two dashes|
This classic recipe first appeared in O.H. Byron’s 1884 Modern Bartenders’ Guide, and is considered something of a bridge between the Manhattan and the Martini (two equally historic cocktails).
Historically, the ratio of gin to sweet vermouth varies, and is something of a template for a crafty bartender: be sure to tinker with it to find your (and its) sweet spot.
