Narezushi

fish and rice fermented together, the oldest form sushi took

Fish salted and packed with rice for a long lactic fermentation — thought to be the oldest form sushi took. Some eat the rice too, others discard it and eat only the fish, sharply sour and pungent either way.

Lineage

What it's made of

Salted fish is packed into a barrel together with cooked rice. The rice serves mainly as a fermenting bed rather than something eaten on its own. Over months to more than a year of lactic fermentation, the fish takes on a sharp sourness and distinctive pungency, while the rice breaks down into something closer to porridge.

How it's made

Fish is scaled and gutted, salted heavily, and left to cure for weeks to months. Once rinsed of salt, it's layered with cooked rice in a barrel, weighted, and left to ferment over a long stretch. How far the fermentation goes depends heavily on temperature and the season it's begun, and the exact curing time varies by household and region.

Why it took this shape

In an age without refrigeration, combining salting with lactic fermentation is thought to have been chosen across many regions as a way to keep fish for the long term. One theory traces the method back to fish-preservation techniques that developed alongside rice farming on the Southeast Asian mainland. In Japan it's said to have developed independently around whatever fish each region's rivers, lakes, or coast provided — Lake Biwa's funa-zushi, Yoshino's ayu-zushi, and Akita's hatahata-zushi among them.
