I wish some of these cooking competition reality shows would declare this kind of thing. One recent competition one "Is It Cake?" constantly trucks out these sort of demonstration items where some true wizard behind the scenes is making a ton of lifelike items that the actual contestants have to guess about just to determine their own order/ranking in the competition. I always wonder what happens to all of the cake from just that portion of the show (and some other segments). The 'Kraft services table' in the back much be epic etc

I read an interview from the British Baking Show which said that all of the crew knew to keep a spoon in their pocket so they could sample the dishes at the end.
