1. As you said, it tastes sour, sweet, cold and refreshing. The first thing I think of is the cold noodles in North Korea, because there are fruits and vegetables, tomatoes, pear strips and so on. Among the side dishes, there are famous kimchi and spicy cabbage in North Korea, so it is sour and sweet. Because it has not been thermally processed, it can be chilled according to personal taste, so it is very cool.
2. Korean cold noodles are a kind of traditional ethnic food which is well-known at home and abroad and deeply loved by people. Generally, beef soup or chicken soup is used, and the side dishes are spicy cabbage, sliced meat, eggs, shredded cucumber and pear strips. When eating, first put a small amount of cold soup and a proper amount of noodles in the bowl, then add seasoning, and finally pour the soup again. Its noodles are thin and tough, and its soup is cold, sour and spicy.
There is a snack that tastes sour and sweet, cool and refreshing. I know its name. This is bean jelly. Put it in the refrigerator. You can add vinegar and brown sugar, watermelon and raisins to the bean jelly in the bowl. Stir it while eating. Very delicious.
Fortunately, I have been to India, and I have seen a very exciting snack on many streets in India. The people who bought it all ate bite by bite and enjoyed themselves. Later I learned that this seemingly dangerous food is called "flame betel nut". In our opinion, when a group of burning food is put into your mouth, only magic shows will happen, but Indians are used to it. This eat areca way is very popular in India. The flame betel nut snack is to wrap the rich stuffing with betel nut leaves, then light the betel nut leaves with a lighter and feed them directly to the customer's mouth by the boss. The action is very rapid, and the flame entrance goes out. Diners describe flame betel nut like this: it tastes cold and cold, refreshing and fast, sour and sweet, and the throat is very comfortable after eating.
At the sight of the words "sour and sweet", a snack immediately came to my mind, that is "Korean cold noodles".
The Korean cold noodles I'm talking about are not the kind of baked cold noodles baked with cakes, eggs and seasonings. But the kind that likes noodles, soup and water.
The taste of noodles is generally salty, but the taste of Korean cold noodles is "sour and sweet" Why cold noodles? But the noodles are cold, and with sweet and sour soup, they taste cold and refreshing!
This is different from most pasta, which left a deep impression on me. Maybe this snack you are talking about is Korean cold noodles!
