well I eat grinner and it is excellent
1.Fillet the grinner
2. Skin the fillet it, is somewhat hard to skin because it breaks off
3. lay the fillet flat with the inside up and slice a strip off the top above the lateral bones
4. Slice another strip off below the lateral bone
5. Soak the fillet for ten minutes in very salty and i mean very salty water this will firm the flesh do not wash it in fresh water.
6. Mix self raising flour with a lot of salt and dip the wet fillet into the flour /salt mix and fry or deep fry the strip until it is crispy brown serve with chips and with a good mayonaise.
Of course they have bones, but if you crisp them you can eat them bones and all, and they are good chewing, try this method, you'll like them. other fish that fry well this way are whiting , garfish, in fact any of the fine fleshed fish. The heavily salted flour makes them brown and crisp. if you want you can dip the fillet in milk before you flour it but drip it dry before flouring. big grinner are better !! Small ones are a bit fiddly. jimbo99 has eaten everything in the sea (at least once).
