JELLIED EELS - Harrod's Department Store
I first heard of this on Andrew Zimmern's Bizarre Foods show on the Travel Channel. So of course I had to see for myself.
Yes, they looked exactly like you imagined. Chopped up bits of eel suspended in clear gelatin. I actually read that historically eels were quite abundant in the Thames and were a common food source.
Where these particular eels hailed from I have no idea. Did I try them? Um, no I did not. If they had lime flavored jellied eels on the other hand...
