The canned herring does smell particularly smelly, and even some people smell this flavor will feel particularly disgusting, but now like to eat this canned food is still particularly more people, the first reason is because the nutrients inside this canned food is really more, the second reason is that this canned herring does not smell very good, but eat it is actually quite fragrant, with the durian is a reason. The 2nd reason is that this kind of canned herring doesn't smell very good, but it still tastes quite good, just like durian. The 3rd reason is because eating canned herring has become a habit or a custom in some areas.

In fact, the earliest canned herring came from Finland, where the population was not particularly large, less than 1 million people. Of these one million people, about 200,000 were engaged in fishing at the sea. From April to June each year, these people could catch a large number of herring, which they couldn't eat by themselves because of their large quantity, and they didn't have advanced refrigeration technology at the time, so the Finns thought of using fresh herring to make canned herring.

The process of canning was very simple, with the herring cleaned and soaked in salt water, then boiled over low heat for a period of time, and then canned directly into the cans. The Finns would sell the canned herring to other regions to make a profit, and because the conditions were not particularly good, people slowly developed the habit of eating canned herring, which is still a habit in many regions today.

But one thing is for sure, the taste of this kind of canned herring is really not very good, and many people may not have the courage to try canned herring at all. But it is also because of the herring reputation is relatively big, so there are a lot of people will deliberately come to the challenge of eating this canned food, so that the sales of canned herring is instead more and more high. Of course, the nutritional content of this fish itself is also relatively high, although the canned herring is really not very tasty, but the nutrition is really very comprehensive.
