微生物で解毒? 日本人の発酵への執念が生み出した珍味

A delicacy born from the tenacious pursuit of the Japanese to expand the benefits gained from fermentation to the extent of utilizing microorganisms as detoxifiers!
Blowfish ovary is known to contain a deadly toxin called tetrodotoxin. The native residents of the Mikawa district have been long treasuring an ultimate recipe to detoxify the ovary through fermentation and change it into a delicacy filled with umami. The ancient originator of this recipe found out that by keeping the ovary in salt for a year or so, and pickling it further in bran for another year or two, the deadly tetrodotoxin will get purified. This was a discovery that would not have been found if the originator of this recipe did not attempt to apply the technique of heshiko (fish pickled in rice-bran paste) that was already widely popular in the Hokuriku region to ovary that was considered a deadly organ in the blowfish that nobody ever dared to eat. Fully fermented blowfish ovary emits a bright pink color that draws a sharp contrast with the rustic wooden barrel filled with the bed of salt or rice bran paste used for its pickling. This is an amazing invention of the people in Kaga clan that reflects their enormous amount of passion, imagination and tenacity to develop its own local specialties.
