The description is not satirical. It is very, very accurate.
The first time I had Natto was in Japan when I was staying with a host family. They served it to me at 11 am as 'lunch' along with some very delicious food.
Now, just FYI.. im not queasy at all about food. I've eaten fried grasshoppers, roasted ants, I love raw fish and seaweed and literally I'll eat almost anything and try any food. When I was told its fermented soybeans all I could think of was 'neat! ill have some of that!'.
Big. Big mistake. To this day Natto is the ONE food.. the ONE food I will never touch again.
The smell was very strong and yes, it smells like something that's gone bad. Well, like something that went bad quite some time ago. But that didnt stop me from trying, i've eaten things that smelled worse and were wonderful.
But no. Natto...
its like something that crawled into a sewer and died there last week. The smell, the texture, the taste.. absolutely revolting. It was sheer willpower and the thought of how embarassing it would be if I puked over my host family's dinner table that kept me from violently returning the natto back into its container.
also of note, much later in that trip at a restaurant I had the guts to try it again..thinking maybe the host family had given me a super-strong version of natto.
never again.
