I thought you people were weaned on mushy peas up your way?
For the record, I was raised eating 'garden' peas. My Dad wouldn't have touched mushy peas and I doubt he had even heard of them.
I doubt I had eaten mushy peas until I had left home and gone to uni. I think my first experiences of mushy peas would have been in mushy pea fritters during drunken, late night, fish suppers.
I bet it didn't breed up there, though!
