I split the bitters between the shaker and the glass because I like to fortify the flavor of the bitters in this drink.
You may, of course, use bourbon instead of rye. I prefer rye. The ratio of whiskey to vermouth can vary from about 4:1 to 2:1.
Also, you can substitute Peychaud's or orange bitters.
