Toast to the fall season with this cocktail from Duane Fernandez Jr., the resident mixologist at Entwine in New York's West Village.
Smack a handful of mint to release the oil (no muddling!).
Add all of the ingredients to a pint glass and shake vigorously.
Strain, and serve into a Martini glass, or strain and serve over fresh ice in a highball glass. Garnish with a mint sprig.
