Cambridge is a long way from East London, Bobbi … in more ways than one. Actually, I doubt you’d get pease pudding in London now. It’s an old fashioned thing.
Black pudding was eaten too. I think that’s still fairly widely available in supermarkets …. if you like that kind of thing. :o/
I don’t think white pudding was a London thing though. I think that’s more a northern ‘delicacy’. It’s a ‘no’ from me for all of it.
Do you have faggots in the north? That’s another old East End thing. They’d eat saveloys with those too. Made of innards I think and very savoury.
