Going back a few years as an engineer on the road, you couldn’t even get proper fish cakes in the rest of Yorkshire, let alone the rest of Britain. Just the same when you’d ask if they’d got any Hendos, you got offered Lee a& Perrin.
Fortunately things have changed a bit now and most towns in Yorkshire plus the more local seaside resorts offer both and they even call them YORKSHIRE fish cakes here on Chessy.
