It is, though I cannot truly attest to whether or not it's any good. Supposedly, when created by the right chef, it is very enjoyable. But the way my mother managed to turn it into...

[What's the word he's looking for here...]

...bitter mush...makes it rather unappetizing. Combined with adding fruits and other vegetables as well as nuts, seeds, supplements, even things such as honey...

[The look on his face makes it seem like he's reliving this particular food trauma. Do you know how bad that is, Fuyuhiko? A bitter, mushy dish with crunchy or sweet elements, or bitter supplements, or syrup.........he may have shuddered just a little bit there.]

I hesitate to actually try it made by anyone else.

[Like...there are not many things he isn't willing to try but that one thing in particular...]
