Guests gathered in murmuring clusters in front of the bar, but I wasn’t quite ready to dive into conversation. In honor of the occasion, and as friends and family of the bride and groom trickled in, gingham- and denim-clad bartenders were busily shaking up a trio of specialty cocktails. I needed a serious pick-me-up, so I found a quiet corner of the bar and ordered the aforementioned Sazerac. It arrived frosty and frothy in a chilled glass, giving off a faint licorice aroma and glowing with a pale yellow-green light. A few sips in and both my mood and shyness began lifting. I felt buoyed up by the lilting, balanced marriage of what I later discovered to be rye whiskey, green chartreuse, lemon bitters, and just the barest hint of absinthe. Intoxicatingly fresh and subtly smooth, I made it my signature drink for the rest of the day.
