WATCH: The art of preparing fugu - the toxic Japanese puffer fish
You might know fugu, the toxic puffer fish that was once the subject of an episode of The Simpsons.
It's considered a delicacy in Japan and China, despite containing enough poison to be fatal to 30 adults.
Chefs need a special licence to prepare it and must undergo a ten-year apprenticeship before handling the fish.
YouTube channel , Great Big Story, spoke to fugu expert Yutaka Sasaki, a chef with more than 45 years experience preparing the raw fish.
The video explains how he prepares the potentially lethal dish.
“It’s an indescribable taste,” Sasaki explains. “It’s mysterious, it’s delicious. Really delicious.”
While they may take all precautions necessary, the puffer still causes several deaths each year.
In 2015, five Japanese diners were poisoned in one sitting after allegedly eating the liver of the puffer fish.
It is the liver as well as the intestine and ovaries which are usually banned from restaurants and if eaten in any significant quantity, the poison can paralyse muscles, suffocating victims.
