I guess this is a presentation variation of Brulot--
You cut a long continuous strip of lemon or orange peel and stud it with whole cloves(about 1 every inch), stick it on the end of a long-handled fork or skewer.
When it comes time to flambe the pan, make sure you are away from people who might get splashed, hold up the strip so the bottom end is in the pan, dim the room lights, and ladle the flaming liqueur onto the strip held over the pan(CAREFULLY, NOT TO SPLASH IT) and slowly pour a stream of flame down it--the cloves ignite and glow briefly--like devil's eyes (hence, "Diablo")
Do it a couple of times, then extinguish the flaming pan with hot coffee and serve in small cups. You can leave the peel in the pot for flavor.
It's not the destination, but the journey!
