The Sazerac is a classic New Orleans cocktail dating back to the 19th century, often considered one of America's oldest mixed drinks. Traditionally made with rye whiskey (originally cognac), a sugar cube, Peychaud's bitters, and an absinthe rinse, it is served neat in a chilled glass and garnished with a lemon twist. The Sazerac is renowned for its strong, aromatic flavor and holds a significant place in cocktail history.
