Heat 1" vegetable oil in large skillet to a medium/medium high heat. Mix flour and essence together in a pie plate.
Skewer bacon and liver pieces alternately, entwining the bacon with the liver
(So if you're looking at the side of the skewer, the bacon is in an "S" shape with liver in the curves. I hope this makes sense)
Then dredge the skewer in flour mixture...Place skewer in hot oil 3-4 minutes on each side, let drain on paper towel, sprinkle with salt and serve.
