Yaki-saba no Nitsuke (Grilled Mackerel and Onion Simmer)
A mackerel that has already been grilled whole is broken into large pieces and simmered a second time with onion. In inland Tottori, grilled fish kept and traveled well, and cooking it again this way became the habit. Even with the head and backbone gone, small bones stay in the grilled flesh, and a fingertip run along it finds them. Ginger is used twice: thin slices go into the broth, and fine shreds go on top.
