It is a traditional delicacy that the people of northern Sweden are proud of. It was also the national ration for the Swedish army led by Emperor Gustav the Great during the Thirty Years' War. However, some international airlines prohibit passengers from taking it on board. It is said that there is a risk of explosion when it encounters high air pressure! It is the "edible biochemical weapon" that has defeated countless heroes - canned herring.
It is not like stinky tofu or durian, which smells bad but tastes delicious; nor is it like Laoshan White Flower Snake Grass Water, which has no smell but makes you stomach upset after drinking it. Canned herring is as smelly as it is on the outside and inside. From the moment you get it until the day after you eat it, you will have an "unforgettable aftertaste"... Wherever it goes, there is no grass and its combat power is amazing, and its combat power is even 20 times that of a dead mouse! Even professional mouse hunters can’t stand it.
If you are looking for a certain treasure to purchase on your behalf, the seller will definitely package it tightly like this. Because the smell of canned herring is too strong, you have to open the can outdoors to avoid disturbing others!
The explanation given by scientists about this invincible taste is this: the peculiar smell comes from anaerobic bacteria called "Haloanaerobium" produced during fermentation. In addition to producing carbon dioxide, it also produces odorous chemicals such as acetic acid, propionic acid, butyric acid, and hydrogen sulfide.
According to a Zhihu netizen "Lin Yuan Ye", after opening the can, an indescribable smell filled the air. How to describe it... It was like a thousand-year-old corpse farted... The stench that I had only smelled before rushed directly into my nose, and my mood was shattered. For a moment, I even doubted whether I was really eating shit. Compared to that, stinky tofu and bean juice are naive! That kind of smell can only be compared to shit.
Faced with such an unacceptable smell, if you can still eat it without changing your expression, that’s really good.
