The British are mad about curry - 'Ruby Murray' in Cockney rhyming slang.
Alkarim Jivani speaks to curry lovers north and south of the border to find out how curry came to be so intimately linked with the British sense of identity.
Historically, the English have been seen as distrustful of foreigners and wary of foreign food.
So the nation's long love affair with curry - which is as much working class as colonial - is a surprising one.
Even more curious is how this passion for curry is now recognised as part of the British identity.
Vindaloo was the unofficial song of England's 1998 World Cup team - an unlikely battlecry for English football fans.
In 2001, Robin Cook, then Foreign Secretary, declared that chicken tikka masala was the nation's most popular dish.
Chicken tikka masala is even included by the Ministry of Defence in its operational ration packs to bring the troops some home comfort.
