Is it shellfish or is it a whitefish? Whatever, you eat the whole thing, heads, tails the lot but this proves to be its strength - flavour. Try rolling them from frozen in seasoned flour then fry them in very hot oil for a couple of minutes, after frying remove from the pan with a slotted spoon and place onto kitchen paper to remove the excess oil, sprinkle with salt and serve with garlic mayonnaise and lemon juice. Enjoy...
