Here’s how classy the Sidecar is: it once had several more ingredients than it now does. But, according to the definitive how-to The Fine Art of Mixing Drinks, the excess was “refined away” over time. What remained was the essence of the drink, all boozy, lemony muscle. For an equally muscular pairing, you’ll find that the Sidecar loves being sipped alongside a meaty Epoisses, which brings out the citrus of the drink, leading to a flavor that evokes a fine duck à l'orange.
