Most modern barkeeps worth their shakers consider this aromatic cocktail the classic of classics—a straightforward whiskey drink flavored with a hint of bitters, a little sugar, and a whiff of absinthe. Though it’s usually made with rye, Kirk Estopinal of Cure gives a nod to the Sazerac’s historical predecessor with a smooth brandy-based variation that features Pierre Ferrand 1840 cognac, a vintage blended to mimic the flavors of early nineteenth-century New Orleans.
