First, the practice of dried cabbage
As the name implies, the main ingredient of this cabbage is cabbage. Because the taste of northerners is sweet, this kind of dried cabbage is sweet. People who often live in the south are not used to going to the north. Take tofu flower as an example. Tofu flower is sweet to northerners, and other sauces are added. The method of making dried cabbage is to drain the cabbage, add fresh sauce and vinegar, stir, add sesame seeds according to your own taste, wrap it in plastic wrap and put it in the refrigerator for freezing. You can eat it directly in about an hour or two. It is more suitable to eat in summer, and it is a good appetizer.
Second, what is it?
When Emperor Qianlong went to the folk, he was inadvertently attracted by this cold dish of street vendors. So he brought this practice to the palace. The emperor may be used to eating delicacies, and occasionally eating some refreshing side dishes can also make him feel comfortable, hence the name. This dish is cold, not hot as the hostess said, because it is drained in advance and cooled before cooking. This kind of dried cabbage is a northern dish. In fact, in addition to this cold dish in the north, there are many in the south, such as cold cucumber and cold edamame, all of which belong to the category of cold dishes. There was no refrigerator in ancient times, but it could be placed at the wellhead for a period of time, which had a certain chilling effect. This time will be more refreshing and increase people's appetite.
In short, if you are interested in this dish, you can learn to cook it and add seasoning according to your own taste.
