You mean natto? A few weeks back, I caught the judging segment of the Japanese Iron Chef with natto as the featured ingredient. Only one of the judges said he liked natto.
I had to look it up at the time.
From what I gather, the Japanese Iron Chef series had a theme of traditional v. modern Japanese cooking. The modernists were apparently winning.
I was thinking of the Thai equivalent. I’ve never had occasion to be near either.
