A georgous bourbon negroni-style drink! I rate few drinks as a 5.0, but I rated the Boulevardier (Stagger Lee) as a 5.0 without hesitation. I noticed one user said "First sip screams bitter..." Myself, I made sure to use less than 7/8 oz of Campari, just to avoid issues of bitterness. The same user judged the drink perhaps too sweet toward the end of the drink, and suggested using rye instead of bourbon. I'm guessing the sweetness is due to the Cynar becoming more prominent as the large ice rock melted, and the drink became diluted. I avoided this by simply stirring with ice until cold (~30 seconds) and then pouring the drink into a chilled glass. In other words, I didn't use any ice after stirring. Thus, the drink's taste remained uniform, from beginning to end. And it was great!
