1 oz Bourbon
3⁄4 oz Campari
3⁄4 oz Sweet vermouth
1⁄4 oz Kummel
Stir with ice and strain into a cocktail glass.
Recipe specifies Diabolique brand bourbon and Lacuesta brand vermouth. I made it with Eagle Rare 10 yr and Carpano Antica Formula and thought it worked well.

Just an FYI here, Diabolique is an infused bourbon, so it's not replaceable. That said, if the drink works with regular bourbon, it works - though I would call this an altered recipe.
