2.Fugu
Fugu is what we normally call puffer fish and it is no mystery that it is indeed a poisonous dish!
The internal organs of the Fugu contains deadly amounts of the poison tetrodotoxin for which there is no known antidote!
The poison exist so other sea creatures do not eat the puffer fish, however, humans seem to have not gotten the message.
For the puffer fish to become consumable it needs to be cut “just right”. However, “just right” means that little poison is left in the flesh- not enough to kill you but enough to numb your tongue!
