A researcher behind a study of wasabi's effect on cognition says he knew the fiery condiment had health benefits, but "the dramatic change" in memory was a surprise.
Now the question is, has anyone here actually had wasabi?
But here's the rub: That tangy paste served up at nearly all sushi bars — even the ones in Japan — is almost certainly an impostor. Far more common than the real thing is a convincing fraud, usually made of ordinary white horseradish, dyed green.
Japan doesn’t even produce enough to fulfill their own demand, I’m almost certain all Wasabi I’ve ever had was fake.
I like it in small amounts in sushi, plus in a few other dishes (like my "undead raising" lamen. It gets wasabi, black pepper, red pepper and ginger. If whatever you have ends killing you, don't worry - the mix will make your body move again!)
