I wasn't quite sure what to make of this. It didn't make sense to deep fry a chicken cutlet only to later stick it in a clay pot that would just make it all soggy. But apparently this is one of Ootoya's signature items, so I grabbed one to see if it were any good.
To my surprise, this actually worked. Sure, the breading was pretty much obliterated, but the mildly sweet taste of the sauce complemented the grease (and a generous portion of daikon oroshi never hurt either). I could eat this again, even if I still prefer a more classic crispy tonkatsu.
