I had a "Carlito's Way" last time I was at Casa Fuente in Vegas, and it is now one of my all-time favorites.
1½ ounces Stoli Vanil vodka
¾ ounce Kahlúa coffee liqueur
A single shot of espresso
1 whole cinnamon stick for garnish
Combine all ingredients in a cocktail shaker with ice. Shake vigorously and strain into a chilled cocktail glass. Garnish with a stick of cinnamon.
Onct upon a time when I was stationed at Ramstein AB, FRG I had a cup of coffee in hand and was walking by the First Sergeants office. He yelled, "Come in here, LT!" He took my coffee cup and it disappeared behind his desk. I heard a glug-glug-glug then he handed it back to me. He had topped off the cup with Tullemore Dew Irish Whisky. That brightened my day considerably. That was back in the old days when such things were acceptable in the military. Sadly, those days have long perished.
