Ama-ebi
northern shrimp, its raw sweetness building after it's caught
The common name for the northern shrimp. It's said to carry little sweetness while alive, only developing it after landing as amino acids build up — and the head, often fried whole rather than discarded, carries a rich flavor of its own.
Lineage
What it's made of
A soft-shelled shrimp whose meat comes away easily. Eaten raw, it carries a sweetness said to come from amino acids like glycine and alanine — reportedly the source of its 'ama' (sweet) name. A melting texture is its hallmark, and the larger females are said to suit nigiri best.
How it's made
The shell is peeled and the vein removed before it's laid across nigiri as is. It's said to carry little sweetness right after being caught, only growing sweet as protein breaks down into amino acids over the following hours — meaning the moment it reaches a shop's counter is often its peak. The rich paste inside the head, sometimes called 'shrimp miso,' carries strong flavor and is often used separately, deep-fried.
Why it took this shape
Before refrigerated and frozen distribution matured, it's said to have been difficult to carry raw shrimp far enough for its sweetness to build before serving. Better transport and storage are thought to have made it possible to hold the shrimp long enough after landing for that sweetness to develop before it reaches nigiri.

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.
