Like a Moscow Mule, but better! The gin adds complexity that vodka could never, while combining well with the mint, lime, & ginger. Used Hayman's London Dry, Domaine De Canton, & Goslings Ginger Beer.
As proud owner of a bottle Chartreuse Elixir I tried to add a dash to this cocktail, which imho worked really well. This drink gets a bit more depth without being less refreshing.
Here was my adapted spec, which I think worked really well:
Ingredients
* 4 oz ginger beer
* 1.5 oz gin (London Dry style - Tanqueray)
* 1 oz simple syrup
* 0.75 oz lime juice
* 8 mint leaves
* Garnish: mint sprig
Steps
* In a shaker, gently muddle the mint leaves, simple syrup, and lime juice. Add the gin and shake with ice. Double strain into a highball glass filled with ice. Top with ginger beer. Garnish with the mint spring.
