An Old Fashioned is a classic whiskey cocktail that has been around for over 200 years. It is made with just a few simple ingredients, including whiskey, sugar, bitters, and an optional garnish of orange peel or Luxardo cherry. The recipe for an Old Fashioned can vary slightly depending on personal preference, but the basic steps involve muddling a sugar cube with bitters and a splash of water or club soda in a rocks glass, adding whiskey, and stirring with ice until chilled. Some recipes call for using simple syrup instead of a sugar cube, and others suggest using rye whiskey instead of bourbon for a slightly spicier flavor. Ultimately, the best whiskey to use in an Old Fashioned is the one you like the most.
