I prefer a simple Old Fashioned (i.e. not much fruit). I'll use one sugar cube and add a few shakes of bitters (the three I keep on hand are Angostura, Peychaud's, and Fee Bros Orange but there are many other options). I add a teaspoon of water and muddle until the sugar is dissolved. Then I add a large chunk of ice, a couple of ounces of bourbon (something like Evan Williams BIB or Rittenhouse Rye BIB), and express the oils from an orange peel before adding it as a garnish. As I said, I don't like too much fruit because I like tasting the bourbon. Sometimes I'll light a lighter or match and hold it over the drink before I express the orange peel. The oils are flammable and it's kind of a cool flourish if people are watching.
