Engawa
the fin-moving muscle strip along a flatfish's edge — fatty and prized
The muscle strip running along a flatfish's back and belly edges, used to move its fins. Fatty and crisp-textured, it's a cut only a small amount of which comes from any one fish — long treated as a flagship premium topping.
Lineage
What it's made of
A muscle attached to the fin-supporting bones running along a flatfish's back and belly edges. Because it's worked constantly to move the fins, it carries good fat, giving it a sweetness alongside a crisp, springy bite. The engawa from a true flounder is said to be especially scarce and has long been treated as a premium topping. Engawa from larger flatfish like Greenland halibut and Pacific halibut also circulates commercially, and the muscle is said to be worked constantly enough by the fish's own movement to build noticeably more fat than the rest of the body.
How it's made
A thin strip is cut from along the back and belly edge of a single flatfish. Because so little comes from any one fish, several strips are often laid side by side to make up a single piece. Reading how well the fat has developed and slicing it thin to make the most of its texture is said to be the core of the work. Some shops lightly sear it first to melt the fat before serving.
Why it took this shape
A flounder's engawa yields only a small amount per fish and has long been treated as a premium cut. In recent years, the use of large imported flatfish is said to have made it possible to offer engawa cheaply even at conveyor-belt chains and supermarket sushi packs, changing how a once-scarce cut is treated today. The fat's quality and quantity are said to vary noticeably by species.

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.
