A friend of a friend told me that he was traveling through Asia. Then once he ordered a meal in a restaurant. He couldn't understand what it was. So he first got a good stock. Afterwards a waiter brought a turtle that was placed in the hot soup. Obviously, the turtle got very scared and defecated and urinated into the soup. Then the turtle was removed from the soup and the meal was finished. My personal opinion on this meal doesn't matter here. I'm just curious if this story could be true and if, how the meal is called and where you would have to go to get it.
After quite a bit of research, I wonder whether this isn't some sort of weird combination of stories.
Turtle soup exists. That's not under debate. For this you need to go to China or the US, especially in Louisiana.
Now most commonly, turtle soup in China is made with soft-shelled turtles. This is important, because they can urinate through their mouths when dipped in water!!
Now given that a lot of animals are prone to wetting themselves when frightened, then it would stand to reason that if instead of cooking the turtle, you dipped it in the water, it might well pee /poop in the water....
One other less sanitary means of doing it is demonstrated on this link, although it's not particularly kind to the turtle.
