I really, really tried to like nattou but nope, not successful. I tried to eat it as it is, with karashi, with soy sauce, mixed in a lot of rice. Still hate it. I introduced it to my Japanese class as part of a "cultural immersion" so my students would be aware of other Japanese food that are out there and they won't be limited to just the usual sushi, donburi, etc. To make it fun, we had a contest: i separated the class into pairs and the pair that can eat the nattou fastest will get a prize. The prize package included origami paper packs, cute Japanese erasers and stationery, Pocky...and more nattou I also do not like umeboshi because it's so sour. I make bentos and the first time I made a hinomaru bento, I didn't even eat the umeboshi. I gave it to my boyfriend. I have not tried the more exotic ones like kanimiso and horse meat.
