chicken — chopped, battered, fried chicken with a sweet orange flavored chili sauce that is thickened and glazed. The traditional version consists of stir-fried chicken in a light, slightly sweet soy sauce flavored with dried orange peels. Wonton soup — In most American Chinese restaurants, only wonton dumplings in broth are served, while versions found in China may come with noodles. (In Canton, it can be a full meal in itself, consisting of thin egg noodles and several pork and prawn wontons in a pork or chicken soup broth or noodle broth). Especially in takeout restaurants, wonton are often made with thicker dough skins, to withstand the rigors of delivery. Regional variations New York City The New York metropolitan area is home to the largest Chinese population outside of Asia, which also constitutes the largest metropolitan Asian-American group in the United States and the largest Asian-national metropolitan diaspora in the Western Hemisphere. The Chinese-American population of the New York City metropolitan area was an estimated 893,697 as of 2017. Given the New York metropolitan area's continuing status as by far the leading gateway for Chinese immigrants to the United States, all popular styles of every Chinese regional cuisine have commensurately become ubiquitously accessible in New York City, including Hakka, Taiwanese, Shanghainese, Hunanese, Szechuan, Cantonese, Fujianese, Xinjiang, Zhejiang, and Korean Chinese cuisine. Even the relatively obscure Dongbei style of cuisine indigenous to Northeast China is now available in Flushing, Queens, as well as Mongolian cuisine and Uyghur cuisine. The availability of regional variations of Chinese cuisine coming from so many provinces of China is most apparent in the city's Chinatowns in Queens, particularly the Flushing Chinatown (法拉盛華埠), but is also notable in the city's Chinatowns in Brooklyn and Manhattan. Kosher preparation Kosher preparation of Chinese food is also widely available in New York City, given the metropolitan area's large Jewish and particularly Orthodox Jewish populations. The perception that American Jews eat at Chinese restaurants on Christmas Day is documented in media. The tradition may have arisen from the lack of other open restaurants on Christmas Day, the close proximity of Jewish and Chinese immigrants to each other in New York City, and the absence of dairy foods combined with meat. Kosher Chinese food is usually prepared in New York City, as well as in other large cities with Orthodox Jewish neighborhoods, under strict rabbinical supervision as a prerequisite for Kosher certification.
