Miso-Flavored Simmered Mackerel

In Japan, saba, mackerel, is often simmered in a rich broth flavored with brown miso, whose strong flavor suppresses the oily flavor of mackerel. Personally, I prefer salt-grilled mackerel, in which I can taste the true natural flavor of this fish. But from time to time I enjoy using this recipe of my mother’s for delicious miso-flavored mackerel.
