The style of cuisine known as "Indian Chinese" has its roots in Kolkata. People from the Hakka and Cantonese communities started coming to India in the 18th century to work in a sugar mill under the British. These immigrants began selling dumplings, dim sum, noodles, and rice as street food to sustain their families. Over the years, a distinct style of Chinese cuisine suited to Indian palates emerged, blending Chinese cuisine with Indian flavours and spices (also, many ingredients found in China were not available here). One example of this mash-up and adaptation is Chicken Manchurian, which is ubiquitous on the menus of Indian Chinese restaurants, and one of the most popular Chinese dishes in India. Nelson Wang, a third-generation Chinese chef born in Kolkata, invented the dish.
