When local people cook local food by themselves, they not only have experience, but also get help from relatives and friends. Because local food is often eaten by many people in the local area, everyone actually has their own views on this kind of food. Everyone knows what the taste is missing as soon as they eat it, so the local food they eat in the local area has been tested by the local people, and they also know whether the food is authentic or not.
When a delicious food spreads to other places, many people will cook it in a gourd painting gourd ladle way. They can only use recipes collected online, but there is no experienced person to guide them, so the taste is definitely different. After all, they have eaten it once or twice at most before. How can they really imitate the taste? For example, the very popular snail powder and Chongqing hot pot are difficult to make local flavor in other places, and only when you have been to the local area can you eat the most authentic original flavor.
Moreover, there are no local raw materials in other places, and many raw materials are locally produced, which is more authentic and fresh. Like sour bamboo shoots, they are generally native products of Guangxi. If you are abroad, you can't eat sour bamboo shoots that taste so good at all, and even have a bad smell. But the local pickled sour bamboo shoots actually don't have those tastes.
Therefore, many local dishes need to go to the local area to get the most authentic taste. Sometimes what you eat in other places is fake. So if you want to taste delicious food from all over the country, you need to travel and feel it yourself, otherwise you won't be able to eat it.
