Espresso Martini
This Espresso Martini is just one of many coffee-flavored Martini recipes being made today. We like this one because it uses chilled espresso that gives it a caffeinated kick which you just can't duplicate with coffee liqueurs alone. If you want to step it up another notch, use an espresso-flavored vodka. This is a fantastic before or after dinner drink, happy hour cocktail, or, really, anytime you desire a great coffee-flavored cocktail.

1 oz. Fresh Espresso
1.5 oz. Vodka
1.5 oz. Coffee Liqueur

Pour ingredients into shaker filled with ice.
Shake vigorously, and strain into chilled martini glass.
It should be somewhat frothy. (Spirits/Cocktails)
