2. Jellied Eels
This traditional Cockney (ie East Londoner) meal has been feeding London’s poor for centuries.
Eels from the Thames river are boiled in water and then allowed to cool.
The water turns into a colorless jelly which encases the eel flesh. Tastes much better than it looks (thankfully).
Unfortunately the custom is dying out due to a combination of reduced eel stocks (hit by flood abatement measures amongst other things) and the change in the ethnic background of East London. So get your jellied eels whilst you can.
