In a skillet, pan fry 10 strips of bacon. Take 2 ounces of bitters and deglaze the pan, scraping the drips from the bottom. Combine with 12 ounces of bitters and refrigerate for the night. Strain the solidified fat from the bitters.
In a mixer, add 3 brandied cherries, 1 cube of brown sugar, and 4 dashes of the bacon bitters. Muddle the ingredients into a paste, then add 1 ounce of Calvados Brandy and 1 ounce of Bulleit Bourbon. Add ice and shake well. Pour into a rocks glass, top with club soda. Garnish with orange twist.
