Flathead are one of the best tasting fish out there. Right up with KG in my opinion.As a chef I would put flathead on the menu as a special and get more comments than any other fish (apart from Atlantic Salmon)Half your luck with the big one. For me good seafood needs very little attention. Cooked simply they taste the best. Leave all the sauces and smothering with herbs and spices for the poorer tasting species. Perhaps fillet, then season with S&P, lightly flour, cook in a little oil and butter, squeeze of lemon or lime, that's all that is needed for a great meal. Batter or crumb is OK, but pan fry like I mentioned and it will taste supurb !
