First, Japan once selected the top ten most smelly foods in the world according to the data, among which canned herring topped the list. At present, the international unit for evaluating the strength of odor is Alabaster. The higher the AUAU value, the stronger the odor. According to the measurement, the stinky tofu in China has an odor value of only 420AU, which is at the bottom of the list. The puffins of the Newt, the canned cheese of New Zealand and the pickled fish fillets of South Korea ranked fourth, third and second respectively. However, the odor value of canned Swedish herring at the top of the list has reached an astonishing 8070A, and there is still a gap between the pickled fish fillets that can be ranked second. Many people once challenged this kind of food because they questioned the results, but many challengers abstained because of vomiting when they opened it. It can be seen that canned herring is indeed at the top of the list by strength. Many people compare the taste of canned herring to a combination of rotten eggs, septic tanks, rotten fish and excrement. Not to mention eating it, even the smell is enough to suffocate. It is no wonder that many people wear gas masks when opening canned herring.
Second, however, this kind of food, which was badly disliked in China, is sought after by everyone in Sweden. Every year, the local people can eat 800 tons, which makes the Chinese people go to their hometown. Then why are Swedes so obsessed with him? In fact, this is mainly related to the local geographical environment. Sweden is located in the culvert, with a long coastline and a large number of flying fish. For local fishermen, fatty flying fish is undoubtedly the best food for wintering. However, because this kind of fish is not easy to preserve, they found another way and spontaneously studied the pickling technology of herring. They soaked the caught herring in salt water, boiled it in warm water and put it in a container for fermentation for several months, making the herring sticky and juicy. Over time, canned herring has become a traditional food with a long history in Sweden. Later, after numerous improvements, canned herring is now available.
Third, although the output of local canned herring is as high as several hundred tons, the export is relatively small, and most of them are self-sold. Many people say that it is because it tastes so bad. Is this really the case? Although canned herring stinks, it's not bad. Swedes say that the reason why some people are jealous is that they can't eat. In fact, the correct way to use it is to open it in clean water, one is to prevent the splash of juice leaves from affecting the air quality, and the other is to clean the herring's excessive seasoning and juice, so as to weaken its pungent taste. Then add the cleaned flying fish and vegetables to the bread for eating. Of course, you can also mix them according to your preferences, so that the canned herring will not be so terrible after being processed and eaten.
