A friend of mine from Xinmin Evening News said that "Du" was originally a word like sound, which was used to describe sound. Hard objects hit each other, saying "loud", and knocking at the door at the knuckles is also described as such. From this, the word "determined" is derived, which means "finalized", "implemented" and "settled". In addition, northerners say that the pot is boiling, and they say that the water is boiling. Jiangnan people describe it as "Benedict" and say that "the water is boiling". From this, another verb "DuDu" is derived, saying "Let this soup have a rest". The word "DuDu" in "Salted DuDu Fresh" means from now on: bacon, fresh meat and bamboo shoots, use slow fire and work hard to "DuDu". It seems that there is no contradiction between the explanations of the cabinet mother and the intellectuals. In short, this is a kung fu dish, which needs to be "mastered" slowly. It's probably because it's slow to learn, so it's not available in ordinary Shanghai restaurants.
In fact, pickled vegetables are not necessarily the patent of Shanghai cuisine, but Shanghai people are more authentic. It should be the housewife's housekeeping dish in the south of the bamboo forest. I have seen a picture of spring bamboo shoots by Jin Nong, one of the "Eight Eccentrics of Yangzhou". The poem on the picture says: "The first spring thunder hits at night, and the mountains are covered with new bamboo shoots and jade edges. Buy pork with boiled flowers, don't ask the cook to ask the old monk. " Jin Nong's poem is so exciting that it is mischievous and even mischievous. I don't want to talk about it. I just want to know what the phrase "buy pork with boiled flowers" is. It can be seen from the poem that the bamboo shoots bought are spring bamboo shoots, not winter bamboo shoots. Winter bamboo shoots are precious, and people in Beijing call them "Yulan slices". Generally, they are cut into shreds and fried with shredded pork, or fried with cabbage and shepherd's purse. Winter bamboo shoots are expensive, but spring bamboo shoots are cheap. Spring bamboo shoots are big and can be cut into large pieces for cooking pork. In this way, there is no doubt that Jinnong's dish is pickled and fresh. It can be seen that everyone in Jiangnan knows pickled and fresh, and all the cupcakes in Jiangnan will cook pickled and fresh food. It's just that this naughty farmer only greets the old monk without asking the cupboard mother. I can't do it. I'm going to the Shanghai restaurant opposite my home, to ask the kitchen girl in the south of the Yangtze River, and to eat pickled vegetables.
