Think British produced food and you may think of fish and chips or a traditional roast. But if you’re in London, one staple you may want to try is jellied eels, a delicacy which has been produced and enjoyed in the city since the 18th century. The dish is exactly as it sounds – chopped eels served cold in a sort of jelly. 200 years ago, eels were common in the River Thames and the dish was cheap to produce, nutritious and filling. They were often served with pie and mashed potato, another traditional London dish. It became popular in the East End, traditionally the working class area of London, and today is still associated with that part of the city. Unfortunately, there are fewer traditional places serving eels as there once were; one of the survivors is Manze, which has been serving the delicacy since 1902.
