Phenomenal. The added mackerel to the broth makes me feel dirty putting this in the shio category as this is a notable departure from your typical sea salt and chicken broth base. The fish adds complementing aromatics to the salty soup, but doesn’t overpower the dish. The peppercorns were sparse but added surprise pops of texture and spice. I found this light, refreshing, and flavorful. I only wish there were more peppercorns and that the tonkatsu had more character.
