I got gifted some Grand Marnier and needed a drink where I could actually appreciate the taste.
Rather than make a mixed drink and lose the flavor, I decided to make a layered shooter.
The B52 shooter is a classic. Kahlua, Bailey's, and Grand Marnier, layered in equal thirds.
My layering skills need working on, and a proper pony glass would go a long way towards proper presentation, but even when accidentally mixed, it's still a great tasting drink.
