During the British Raj, Britain first started borrowing Indian dishes, creating Anglo-Indian cuisine, with dishes such as kedgeree (1790) and mulligatawny soup (1791). Indian food was served in coffee houses from 1809, and cooked at home from a similar date as cookbooks of the time attest. The Veeraswamy restaurant in Regent Street, London, was opened in 1926, at first serving Anglo-Indian food, and is the oldest surviving Indian restaurant in Britain. There was a sharp increase in the number of curry houses in the 1940s, and again in the 1970s.
