Maybe so, but they make a big deal out of counting down the seconds and showing a very stressed chef who magically backs away at the very last second. At any rate, to me, it looks contrived, whether edited or just completely faked.
Then as I noted the judges get one dish to rate, and take a small bite of some portion of it, then pontificate, then the second dish comes in, not hot by now, then a third comes in some cases. You can't rate food items that way effectively. They should be equally fresh. But, it's entertainment. I guess. Every show seems the same, to me, no matter the title.
