Sushi rice (酢飯, sumeshi; or シャリ, shari in sushi contexts) is short-grain Japanese rice cooked and immediately seasoned with a mixture of rice vinegar, sugar, and salt. The resulting rice is warm, glossy, and slightly sticky — each grain separate but bonded to its neighbours — with a balanced sweet-sour-salty flavour that complements raw fish without overpowering it.
The rice variety
Japanese short-grain (japonica) rice is essential. The high starch content (specifically the amylopectin-to-amylose ratio) produces the stickiness required for sushi rice to hold its shape when pressed. Medium-grain or long-grain rice, including most non-Japanese short-grain varieties, does not bind the same way and will crumble.
Specific preferred varieties: Koshihikari, Akita Komachi, Hitomebore. All produce slightly different texture and sweetness profiles; Koshihikari is the most widely cultivated and available.
Vinegar seasoning (awase-zu)
The seasoning is dissolved before adding to rice:
- Rice vinegar: 3 tablespoons per 2 cups uncooked rice
- Sugar: 2 tablespoons
- Salt: 1 teaspoon
Adjust by preference: Kansai sushi is slightly sweeter, Kanto slightly more vinegary. The seasoning should be noticeable but not sharp.
The mixing technique
Transfer hot rice to a wide wooden container (hangiri, if available). Pour the awase-zu over the rice in a stream while using a rice paddle to fold in a cutting motion — not circular stirring. Fan the rice while mixing to evaporate excess steam and cool to body temperature. Circular stirring activates gluten and makes the rice gummy.
Body temperature rule
Sushi rice must be used at body temperature (approximately 37°C). Cold rice is difficult to shape and becomes brittle; hot rice burns the hands and continues to cook the toppings. The hangiri’s porous wood absorbs excess moisture as the rice cools, contributing to the ideal texture.
Storage
Sushi rice should not be refrigerated — cold temperature stiffens the starch irreversibly. Cover with a damp cloth and use within 4–5 hours.
