The history of Chinese cuisine is marked by both variety and change. The archaeologist and scholar K.C. Chang says “Chinese people are especially preoccupied with food” and “food is at the center of, or at least it accompanies or symbolizes, many social interactions.” Over the course of history, he says, "continuity vastly outweighs change." He explains basic organizing principles which go back to earliest times and give a continuity to the food tradition, principally that a normal meal is made up of grains and other starches(simplified Chinese: 饭; traditional Chinese: 飯; pinyin: fàn) and vegetable or meat dishes (菜; cài).
The Sinologist Endymion Wilkinson sees a succession of incremental and successive changes that fundamentally altered the "richness of ever-changing Chinese cuisine". Four key developments were:
The philosopher and writer Lin Yutang was more relaxed:
Chinese cuisine as we now know it evolved gradually over the centuries as new food sources and techniques were introduced, discovered, or invented. Although many of the characteristics we think of as the most important appeared very early, others did not appear or did not become important until relatively late. The first chopsticks, for instance, were probably used for cooking, stirring the fire, and serving bits of food and were not initially used class eating utensils. They began to take on this role during the Han dynasty, but it was not until the Ming that they became ubiquitous for both serving and eating. It was not until the Ming that they acquired their present name (筷子, kuaizi) and their present shape. The wok may also have been introduced during the Han, but again its initial use was limited (to drying grains) and its present use (to stir-fry, as well as boiling, steaming, roasting, and deep-frying) did not develop until the Ming. The Ming also saw the adoption of new plants from the New World, such as corn, peanuts, and tobacco. Wilkinson remarks that to "somebody brought up on late twentieth century Chinese cuisine, Ghing food would probably still seem familiar, but anything further back, especially pre-Tang would probably be difficult to recognize as 'Chinese'".
