According to a recent survey carried out by Olive magazine, of British food preferences, the most hated food in Britain is Tripe (the lining of a cow's stomach).
The worst 5 were:
2 Jellied eels
3 Deep fried Mars bar
5 Black pudding
Yet ask another group of people and you will find that they love some, or all, of the above.
Taste is a very personal thing.
