Have you tried it yet?
 

Battered Mackerel.

Been a while since I had some. Time for some more. I had whole Mackerel rather than in buns like those south coast. They get small Macks' down south but by the time the Mack's get to the river Tees estuary there's plenty of meat on them not to need a bun to help fill you up.
