What is natto, you ask? Whale snot.
Okay, fine it's fermented soy beans, but it kinda looks like whale snot and it sure tastes like what I imagine whale snot would taste like. It's super healthy, and Japanese people can eat it in boatloads. However, I tried it for the first time and really tried to be tough enough to eat my serving. Well I did, but not before grossing my mom out because I gagged so hard at the dinner table. It's ridiculously stringy (like for a couple of feet) and slimy. It leaves an absolutely bitter vomit taste in your mouth.
The Japanese say that because it's so healthy it contributes to their impressive longevity. Even with my new health kick, there are places I won't go. I guess I inherited my Dad's Osaka tastebuds.
