Before I go on a search in my are to find this true yam, can anyone tell me if there is a difference in flavor (in it's plain, unadulterated form). I'm really curious!

Japanese style: Cook, drain and cool spinach. Compress into a disc shapes. Then spoon thinned (not too) tahini over the spinach and top with bonito flakes!

You guys are killing me!! We can't get it here in Massachusetts.
