I don't know exactly when or how Coca-cola chicken wings became a Chinese dish, but it's a baby compared to everything that originated back when dynasties existed. Heck, many people don't even realize it's a Chinese dish, much less a common one. I have never seen it printed on a restaurant menu or in an English-language Chinese cookbook. It does, however, appear from time to time in Chinese-language cookbooks and on cooking shows, sometimes involving as few as three ingredients. In China, Coke and other sodas hold a higher prestige than they do in the US. About 5 years ago, when I first visited Beijing, some relatives took me out to a pretty lavish restaurant for my first Peking duck experience. After drink orders were taken, the head waiter returned to the table with a wine cart. With a flourish, he brandished a bottle in his right arm for inspection, which, for course, turned out to be Coke instead Bordeaux.
