A slight variation on the classic highball, as served at The Spotted Pig in New York. Lime juice cuts the sweetness of ginger beer and Gosling's Rum while heightening the ginger's sharp bite.
- 3/4 ounce fresh lime juice, from 1 to 2 limes
- 4 ounces ginger beer
- 2 ounces Gosling's Black Seal Rum
Fill a highball glass with ice. Add, in layers, the lime juice, then the ginger beer, then the Goslings. Serve with a straw.
