I've heard of this kind of thing on the Internet. It's a local specialty food. Whether it's cooking delicious food or cold salad, it's a very popular snack for local people. Because it's not available in Northeast China, I specially tasted it when I traveled to Guizhou. It can be said that eating Houttuynia cordata once subverted my outlook on life. Since then, I have never mentioned the word Houttuynia cordata again, and I will not try again.
I can only use two words to describe the taste of this vegetable. I don't know how the local people like this kind of food. Because of the humid climate in Guizhou, the local people can especially eat ginger. Whether cooking or making soup, they will put a lot of ginger, while we northeast people can eat green onions and garlic, but we can't eat ginger. Therefore, they put a lot of ginger and houttuynia cordata in their dishes in Guizhou. During the ten days of traveling in Guizhou, I lost a few pounds.
I think this is also the difference in food. There are too many differences in taste between the north and the south. And Guizhou people especially like to eat sour soup, which is also a special seasoning in Guizhou. Many dishes will be filled with sour soup. People who like him can't help themselves, and those who hate him will feel sick when they smell it, especially putting Houttuynia cordata in the sour soup will definitely make you spit out the meal the day before yesterday.
