Are you a gin or vodka drinker?  Gin is made from Juniper Berries so it has a very distinct flavor that you either love or hate.  If you do not care for gin, please feel free to swap it for vodka.

2 oz. Gin
.5 oz. Creme de menthe
3 dashes Angostura Bitters

In a cocktail shaker filled with ice, add the gin (vodka), creme de menthe and Angostura Bitters.  Shake well and strain into a small martini or coupe glass.
