The ponzu sauces adds a nice flavor. Why not trying simmering pacific saury when you get tired of grilling it? It's also delicious with yuzu ponzu sauce. This was our dinner one day: Yu-dofu (hot tofu) and the main, this simmered pacific saury as a side dish, and rice mixed with umeboshi.

There's no need to simmer pacific saury until the bones are soft as you would sardines, so you can stop cooking it when it's flavored.
The fish is very soft, so don't simmer over high heat. For 2 servings. Recipe by Nanamama
