Key Cocktail

In response to the recent heat wave, the Key Cocktail is a nice refreshing combination of a traditional gin-citrus cocktail with a bit of an island twist.  The addition of the rum and falernum make this a nice cocktail to enjoy in the sun that has enough complexity to get past the basic gimlet base.

Key Cocktail1 1/2 oz gin
Juice of 1 medium lime, about 1/2 oz
1/4 oz falernum
1/2 oz dark rum (other recipes call for 1/4, but I feel the additional helps cut into the lime)

Shake over ice and serve in a chilled martini glass, garnish with either pineapple or lime, enjoy!
