Chilli chicken is an Indian-Chinese dish with Hakka Chinese heritage. Nelson Wang, who was a Chinese immigrant in Kolkata, has been credited with the invention of chicken manchurian, which is very similar to chilli chicken. Kolkata’s first Chinese restaurant, Nanking, was opened in 1924. Other such restaurants followed and before long the cuisine had spread to other cities like Mumbai, from its starting point Tangra, Kolkata’s second Chinatown. Tangra saw a rise in restaurants that wanted to adapt Chinese food to please Indian palates. India’s first Sichuan restaurant opened at the Taj Mahal Hotel in Mumbai in 1974. Chilli chicken cannot be found on menus in China but most Chinese restaurants in India serve it. Even restaurants serving Indian food sometimes add chilli chicken to their menus.
