The sushi vinegar formula
Per 2 cups (360g) raw rice (makes ~4 cups cooked = 4 maki rolls or 2–3 nigiri portions):
- 60ml rice vinegar
- 2 tbsp (24g) sugar
- 1 tsp (6g) salt
Or use pre-made sushi vinegar (Mizkan Sushi Seasoning) at 80ml per 2 cups rice — skip the sugar and salt.
Step 1: Rinse the rice until the water runs mostly clear
Place 2 cups (360g) of Japanese short-grain rice in a large bowl. Add cold water, agitate gently with your hand for 10 seconds, then pour off the cloudy water. Repeat 4–5 times. The water will never be perfectly transparent — aim for translucent rather than milky. The surface starch you are removing would otherwise make the finished sushi rice gummy and clumped rather than glossy and cohesive.
Do not scrub or grind the grains against each other — modern milling removes enough bran that aggressive washing breaks the grains and releases more starch than it removes. Gentle swirling and pouring is sufficient.
Step 2: Soak for 30 minutes (optional but recommended)
After the final rinse, add the measured cooking water and let the rice soak for 30 minutes at room temperature. This allows water to penetrate the grain core evenly before heat is applied, producing a more uniform texture: no hard centers, no mushy exterior. If you are short on time, skip the soak — the result is still good, just slightly less even.
Many modern rice cookers include a built-in soak phase. If yours does, you can skip the manual soak and proceed directly to cooking. Check your rice cooker manual to confirm.
Step 3: Cook with the 1:1.1 water ratio
The standard water ratio for sushi rice is 1 cup rice to 1.1 cups water — slightly less water than regular Japanese rice. The reason: the sushi vinegar mixture you add after cooking contributes additional moisture, so the rice needs to be slightly drier coming out of the cooker.
Rice cooker: use the standard white rice setting, or the sushi rice setting if your cooker has one. Do not open the lid during cooking.
Stovetop: bring to a boil over medium heat, reduce to the lowest possible simmer, cover tightly, and cook for 12 minutes. Remove from heat and rest covered for 10 minutes. See How to Cook Japanese Rice for the full stovetop method.
Step 4: Prepare the sushi vinegar while the rice cooks
Combine 60ml rice vinegar, 2 tablespoons (24g) sugar, and 1 teaspoon (6g) salt in a small saucepan. Warm over low heat, stirring until the sugar and salt dissolve completely — do not boil. Remove from heat and let it cool to room temperature. The vinegar should be at room temperature or slightly warm when it meets the hot rice; cold vinegar shocks the rice and produces uneven absorption.
For the vinegar itself, Japanese rice vinegar is the correct choice. Mizkan, Marukan, and Uchibori are all reliable brands. See What Is Rice Vinegar for a full breakdown of rice vinegar types and substitutes.
Step 5: Transfer to a wide vessel — wood absorbs moisture
Transfer the hot rice immediately from the cooker to a hangiri (wooden sushi tub) or the widest, shallowest bowl you have. A hangiri is ideal because the untreated wood absorbs excess moisture from the rice, contributing to the dry, glossy finish. If using a regular bowl, the rice will be slightly wetter — compensate by fanning more aggressively in the next step.
Spread the rice in a thin, even layer across the surface. Do not mound it — a thin layer allows steam to escape and the vinegar to distribute evenly.
Step 6: Season and fan — this is where sushi rice is made
Pour the sushi vinegar mixture over the rice in a circular motion, distributing it as evenly as possible across the surface. Then, using a flat rice paddle (shamoji) or a wide spatula, fold the rice with cutting motions: slice down through the rice, turn a section over, rotate the vessel 90 degrees, repeat.
Do not stir. Stirring crushes the grains, releases interior starch, and turns the rice into a gluey paste. Cutting and folding maintains individual grain integrity while distributing the vinegar.
Fan simultaneously. While one hand folds, the other hand (or a second person) fans the rice with a hand fan, folded newspaper, or any flat object. The fanning rapidly evaporates excess moisture from the surface of each grain, creating the characteristic dry, glossy sheen of proper sushi rice. Without fanning, the rice looks wet and matte. Fan for 2–3 minutes until the rice reaches body temperature — not hot, not cold, but warm.
Step 7: Cover and use within 2 hours
Cover the seasoned sushi rice with a damp cloth (not plastic wrap — the rice needs to breathe slightly). Use within 2 hours. Do not refrigerate. The starch in sushi rice retrogrades rapidly in cold temperatures, producing hard, crumbly grains that cannot be revived. Room temperature is correct for both quality and the experience of eating sushi — sushi rice should be body-warm or room temperature, never cold.
Ratio adjustments by sushi type
| Sushi type | Rice:Water | Vinegar amount | Notes |
|---|---|---|---|
| Maki (rolls) | 1:1.1 | 60ml per 2 cups | Standard — balanced stickiness for rolling |
| Nigiri | 1:1.1 | 50ml per 2 cups | Slightly less vinegar — firmer grain, should separate when eaten |
| Chirashi (scattered) | 1:1.1 | 65ml per 2 cups | Slightly more vinegar — stands alone as the base flavor |
| Rice cooker | Per machine line, minus 10% | Same vinegar ratio | Many rice cookers have a sushi rice setting |
Sushi rice in practice: three recipes
California roll (inside-out maki)
Lay a sheet of nori on a bamboo rolling mat. Spread approximately 150g of sushi rice over the nori in a thin, even layer, leaving no border — the rice should cover the entire sheet. Sprinkle sesame seeds over the rice. Flip the nori+rice sheet so the rice faces down on the mat. Along the center of the nori (now facing up), lay strips of imitation crab, sliced avocado, and cucumber batons. Roll tightly using the mat, applying firm even pressure. The rice on the outside creates the characteristic inside-out appearance. Cut into 8 pieces with a wet knife — wetting the blade prevents the rice from sticking and tearing.
Nigiri rice base — the 18-gram oval
Professional nigiri uses approximately 18g of sushi rice per piece — roughly the size of a large thumb from the first knuckle up. Wet your hands lightly (a mixture of water and rice vinegar works best — prevents sticking without diluting flavor). Pick up 18g of rice and shape it with gentle pressure into an oval: press lightly, rotate, press again. The goal is a shape that holds together when picked up but separates into individual grains in the mouth — firm enough to transport, loose enough to eat. Pressing too hard produces a dense, chewy block. Too loose and it falls apart when the fish is draped over it.
Place a slice of fish over the oval and press gently to conform. The wasabi goes between the fish and rice — a smear the size of a pea, applied to the rice before the fish is placed.
Chirashi sushi bowl
Chirashi is the easiest sushi format and uses the same rice technique. Fill a bowl with 200–250g of seasoned sushi rice. Scatter toppings across the surface: sliced sashimi-grade fish (salmon, tuna, yellowtail), thinly sliced omelette (tamagoyaki), cucumber, shiso leaf, pickled ginger, and a small mound of wasabi. Drizzle a teaspoon of soy sauce over the fish or serve it on the side. The rice does all the work — the vinegar seasoning and the body-warm temperature make chirashi satisfying even with minimal toppings.

Common problems and what causes them
- Rice too sticky / mushy: too much water (reduce to 1:1.1), insufficient rinsing, or stirring instead of folding when adding vinegar
- Rice not shiny: no fanning during the seasoning step — the gloss comes from rapid moisture evaporation, not from the vinegar itself
- Rice falls apart in rolls: not enough vinegar (it acts as a binding agent), or the rice cooled too much before rolling — sushi rice is worked warm
- Rice tastes too sour: too much vinegar, or vinegar added when rice was already cool (cold rice absorbs vinegar unevenly, concentrating it in spots)
- Rice hard and crumbly after 2 hours: starch retrogradation is natural — sushi rice has a limited window. Keep covered with a damp cloth and do not refrigerate
Frequently asked questions
Can I use regular short-grain rice for sushi?
Yes, any Japanese short-grain rice (koshihikari, akitakomachi, hitomebore) or domestic Calrose works for sushi rice. The critical factor is not the specific variety but the technique: proper rinsing, the correct water ratio (1:1.1), and — most importantly — the sushi vinegar seasoning and fanning step. Premium koshihikari produces a slightly sweeter, more aromatic result, but Calrose from California makes perfectly serviceable sushi rice at a fraction of the price. What does not work: long-grain rice (jasmine, basmati), medium-grain rice from non-Japanese varieties, or any rice marketed as 'fluffy' — these lack the amylopectin content needed for sushi's cohesive texture.
What if my sushi rice is too sticky or mushy?
Three likely causes: too much water (use 1:1.1, not 1:1.2 — sushi rice uses less water than regular rice because the vinegar adds moisture), insufficient rinsing (surface starch creates gumminess — rinse 4–5 times until the water runs mostly clear), or stirring instead of folding when adding the vinegar (stirring crushes grains and releases starch, turning the rice into paste). If all three factors are correct and the rice is still too sticky, your rice may be very fresh (shinmai) — reduce water by an additional 5%.
Can I make sushi rice in advance?
Sushi rice is best used within 2 hours of seasoning. Cover with a damp cloth at room temperature — do not refrigerate. Refrigeration causes the starch to retrograde (recrystallize), making the rice hard, dry, and crumbly. The texture cannot be recovered by microwaving. If you must prepare ahead, make the rice up to 1 hour before and keep it covered in the warmest part of your kitchen. Professional sushi chefs prepare rice in batches throughout service rather than making it all at once, because fresh sushi rice is noticeably superior to rice even 90 minutes old.
Why is my sushi rice not shiny?
The characteristic gloss of sushi rice comes from the fanning step. When you fan the rice while folding in the vinegar, the rapid evaporation of surface moisture creates a thin, glossy coating of gelatinized starch on each grain. Without fanning, the excess moisture stays on the surface, producing a wet and matte appearance rather than a dry sheen. Use a hand fan, a folded newspaper, or even a hairdryer on the cool setting. Fan continuously for 2–3 minutes while a second person folds.
Can I use white wine vinegar instead of rice vinegar?
In a pinch, yes — but reduce the amount by 20% and add an extra teaspoon of sugar. White wine vinegar is sharper and more acidic (roughly 6% acidity vs rice vinegar's 4.2%), so the same volume produces a harsher, more aggressive sourness. The result is acceptable but noticeably different: rice vinegar has a mild, slightly sweet character that complements the rice without overpowering it. Apple cider vinegar is a closer substitute in terms of mildness, but adds a fruity note that is not traditional. For best results, use Japanese rice vinegar (Mizkan, Marukan, or Uchibori).
Does refrigerating ruin sushi rice?
Yes. Refrigeration accelerates starch retrogradation — the amylopectin molecules in the cooked rice recrystallize when cooled below about 4C (39F), producing a hard, dry, crumbly texture that cannot be fully reversed. This is the same process that makes day-old bread stale. Room temperature slows this process, and the vinegar in sushi rice further slows it slightly (acid inhibits retrogradation). This is why sushi restaurants keep rice at room temperature and never refrigerate it. For food safety, consume sushi rice within 2 hours of preparation when held at room temperature.
What is the best rice variety for sushi?
Koshihikari is the gold standard — slightly sweet, aromatic, and with the ideal balance of stickiness and individual grain definition. Akitakomachi is a close second with a slightly firmer texture that some sushi chefs prefer for nigiri. For budget-friendly options, Calrose (grown in California and Australia) produces good sushi rice at roughly half the price per kilogram. Specifically marketed 'sushi rice' in Western supermarkets is usually Calrose or a Calrose blend. All of these are short-grain japonica varieties with 16–20% amylose — the starch profile that produces sushi-appropriate texture.
