Fugu no ko" is a fermented food culture of Kaga, and only Ishikawa Prefecture is allowed to produce it. Since it is the internal organ of the blowfish, even though it is highly poisonous, it can be made non-toxic through a unique traditional process, the mechanism of which has not yet been clarified. Image courtesy of Ishikawa Tourism Federation It is believed that microorganisms break down the poison during fermentation while the blowfish ovaries are pickled and cured in salt for more than three years, but since this has not been scientifically elucidated, it is said to be a miracle food that can be eaten only by continuing to follow the traditional method.
