yeh saw the steamed with lemon pepper thingy on a episode of ifish where the seal filleted it for them!! i would also agree theyre a great strip bait as well.
the main thing with bonito is to bleed them and remove the blood line. Some like them baterred in a cajun batter which is a beer batter with a few spices. sashimi is popular,
i like to rub chilli , paprika a good black pepper and salt and olive oil into the fillet which has been scored and then chargrill it on the coals or bbq it. if prepared right it should go ok!!
cheers pk.
