 Following World War II, curry became even more popular in Britain owing to the large number of immigrants from South Asia.Curry has become an integral part of British cuisine, so much so that, since the late 1990s, chicken tikka masala has been referred to as "a true British national dish".Other British curry derivatives include "Coronation chicken", a cold dish, often used as a sandwich filling, invented to commemorate the coronation of Queen Elizabeth II in 1953 – and curry sauce (or curry gravy), usually served warm with traditional British fast food dishes such as chips.
