So, the story goes like this. One of the contests, Matt, was preparing a pancetta to stuff a quail and in the urgency to get it ready he accidentally slices of the top of his thumb. Now, the thumb unfortunately falls into the pancetta while Matt flees the kitchen scene to get some attention to his now shorter thumb.
The show must go on, so the other chefs take over, fry up the pancetta, stuff the bird, and then feed it to Ramsay. Reports say that the other chefs were not aware of the thumb slicing incident and not wanting to get on the wrong side of the host carried on as they would. Ramsay though was aware of what had happened and let things go on with the following exclamation, "Oh God - finger pancetta."
What is interesting here is that Ramsay then went on to sample the dish and gave it the thumbs up. I guess this is pun intended. A touch of cannibalism may be?
