Shime-saba
mackerel cured first in salt, then in vinegar
Mackerel filleted into three pieces, salted, then cured in vinegar. It's the preparation said to make a fish considered unsafe raw both safe to eat and firmer on the tongue — treated as the signature piece among Edomae's oily 'hikarimono' fish.
Lineage
What it's made of
Mackerel filleted into three pieces. Salt and vinegar together tighten the surface to a faint white and give it a firmer bite than raw sashimi. The oily, blue-fish aroma stays, but the vinegar's tang is said to sharpen its edges. The skin keeps its silver sheen, and it's often sliced with the skin left on rather than pulled off.
How it's made
Mackerel, gutted and filleted into three pieces, is first salted for about a night to draw out moisture and any fishy edge. The salt is rinsed off and the fish cured in vinegar to firm the flesh. The timing and ratio for both stages is said to vary by shop. The pin bones are pulled before it's shaped into nigiri, sometimes served with wasabi or ginger.
Why it took this shape
Mackerel spoils fast and carries a risk of parasites, making it a fish long considered unsuited to eating raw. Curing it first in salt, then in vinegar, is said to firm the flesh while holding bacterial growth back, turning it into something safe to eat. Among Edomae's work on oily 'hikarimono' fish, this vinegar-cure is treated as a signature piece, and laid over rice it's what becomes saba-zushi or batterazushi.

Dishes in the same style
- AkagaiA clam named for its red flesh, colored by blood that carries an iron-based pigment rather than the copper most mollusks use. Prized for its crisp bite, it's a premium topping often substituted commercially with the smaller ark shell relative sarubō-gai, and freshness shapes the work more than almost anything else.
- Akami no ZukeLean tuna cured in a soy-based marinade. Born as a way to keep the fish from spoiling before refrigeration existed, it's said to survive today as its own deliberate preparation even now that fattier cuts get the attention — one of the founding techniques of Edomae sushi itself.
