In a cocktail shaker, combine bacon bourbon, maple syrup, a few dashes of bitters, and ice. Shake and strain into a rocks glass.
If desired, fill glass with ice first. Garnish with an orange peel.
For the Bacon Bourbon
In a medium non-porous bowl or pot (big enough to hold the bourbon) with a lid, combine bacon fat and bourbon. Cover and let stand at room temperature for 6 hours. Place in freezer overnight. Strain liquid from solids using a double layer of cheesecloth set over a colander.
Reserve bourbon and pour back into original bourbon bottle or other bottle of your choice. Discard cheesecloth with bacon fat.
