The old-fashioned is one of the oldest mixed drinks in the cocktail canon. (Original name: whiskey cocktail, which became old-fashioned whiskey cocktail, and then just old-fashioned.) It is a stirred drink, usually built in the glass in which it is served. Both rye and bourbon are suitable base spirits. For the sweetener, purists muddle up a sugar cube with water and a couple dashes of bitters, but simple syrup works as well. Twists can be orange, lemon or both (known as “rabbit ears”). A fruited version of the drink came into vogue after Prohibition and involves the muddling of a cherry and orange slice along with the sugar. That version remains widespread, but we advocate the more elemental rendition that took hold in the late 1800s, one that allows the flavors of the whiskey to shine.
