It is the mustard lotus root that my friend gave me as his souvenir from Kumamoto.
I would say simply about it, putting a lot mustard into lotus root’s holes and then fry it after coat with flour and some seasonings.
Of course may be not only that’s simple though, anyway that’s like it.
It tastes … just spicy, you know, because just a lot of mustard in it.
I think if you like drinking, it’ll be good with it!
