It is thought to be the quintessential British meal, but new research claims the original idea for fish and chips came from Jewish and French dishes.
Fish and chips is a traditional seaside meal
A study of the multicultural nature of UK cuisine suggests the meal was influenced by immigrants 150 years ago.
Professor Panikos Panayi of Leicester's De Montfort University has begun a
£6,000 research project to investigate the global influence on British food.
He said fish and chips mixed "French frites with Jewish fish dishes".
Mr Panayi's research is expected to last two to three years and his findings will be published in a book called The Spicing Up of English Life.
He said: "In the middle of the 19th century the main concern of most sections of
English society consisted of eating enough food of sufficient quality to stay
alive, rather than displaying a concern about variety.
"Transformations between 1850 and 1945 included the emergence of fish and
chips, influenced by both French and Jewish culinary traditions.
He said the origins of the dish were complex, but probably came about from the combination of French frites with Jewish fish dishes.
"It certainly isn't the traditional British food people might think, and of
course the meal is often enjoyed with a cup of tea - the best example of the
influence of the Empire on English eating and drinking habits."
Fish and chips restaurant Harry Ramsden's serves
20,000 portions per day across Britain.
A spokeswoman said: "It's very interesting to hear
the professor's findings on the origins of the ingredients that are still, and
we're sure will always be, a great British tradition."
Mr Panayi has urged people who arrived in the UK in the 1950s and 1960s to contact him to help him with his research.
The project will also examine the arrival of ice cream and pork with Italian
and German immigrants and the effect of the first Indian and Chinese
