An Old Fashioned is a classic cocktail that typically consists of whiskey, sugar, bitters, and ice. The whiskey used can be bourbon, rye, or blended whiskey. The sugar can be a sugar cube or granulated sugar, and the bitters used are usually Angostura bitters. The drink is made by muddling the sugar and bitters in the bottom of a rocks glass until the sugar dissolves, then adding the whiskey and ice, and stirring well to mix the ingredients. The drink is then garnished with an orange twist or cherry. The balance between the whiskey, sweetness, and bitters is important, and the drink should not taste too sweet or too bitter.
