Sushi Rice: what every chef needs to know
Sushi rice is short-grain japonica rice that is seasoned after cooking with sushi vinegar (rice vinegar, sugar, salt) to make sumeshi. Its high amylopectin content (70–80%) makes japonica rice stickier than indica varieties — key to the binding properties of nigiri and maki.\n\nProfessional varieties:\n- Koshihikari (Japan): the benchmark premium sushi rice — sweet, sticky, compact\n- Calrose (California): more widely available in Europe, slightly less sticky but suitable\n- Nishiki, Tamaki Gold: Japanese varieties grown in the US, good quality\n\nSumeshi seasoning ratio (per 720g raw rice):\n- Rice vinegar: 80ml\n- Sugar: 20g\n- Salt: 10g\n\nHACCP CRITICAL: cooked rice at room temperature is a high-risk product for Bacillus cereus (spores survive cooking, grow rapidly between 10–60°C, produce heat-stable toxin).

Sushi Rice: classic dishes
Proven preparations from the professional kitchen — from haute cuisine to global restaurant classics. Use as inspiration for menu development and recipe costing.
Hand-formed rice oblongs (20-22g) topped with fish. The sumeshi rice is the foundation: the quality of the rice determines 50% of the sushi quality.
Nori-rol stuffed with sumeshi and fish of vegetables. the rice bindt the geheel and provides the characteristic sour-zoute smaaknoot.
Hand-formed rice balls with filling, wrapped in nori. Sushi rice provides the binding here as well: the rice must be at the correct temperature when shaping.
Sushi Rice: preparation techniques
Exact temperatures and times for HACCP compliance. Core temperature is leading for poultry and pork.
Rice-to-water ratio = 1:1.1 (not 1:2 as with other rice). Wash the rice until the water runs clear (remove excess starch that makes sushi sticky). Soak for 30 min. Cook with the lid on, never open. After cooking: steam for 10 min with the heat off. Spread on a wooden hangiri (tub) and fold in sumeshi vinegar using cutting motions. Fan for rapid cooling. Rice must NOT be too warm for sushi: 37-38°C is ideal for nigiri.
HACCP-CRITICAL: cold sushi rice becomes hard and sticky and loses shape for nigiri. Hold at 37-40°C in a hangiri covered with a damp cloth. absolute LIMIT: 4 hours at cream temperature. Discard after 4 hours. Never store in the refrigerator: rice hardens and dries out. Prepare small batches for short service periods rather than one large batch.
Nigiri rice: 20–22 g per piece, shaped in 3 motions. Rice too warm (>40°C) sticks to your hands. Rice too cold (<30°C) falls apart. Lightly moisten hands with tezu (water + rice vinegar) to prevent sticking. The fish (neta) must be 0–4°C: the temperature contrast between rice and fish is a quality criterion.
Sushi Rice: HACCP storage and food safety
Based on Codex Alimentarius (WHO/FAO) and EU Regulation 852/2004. Consult your national authority (NVWA/FDA/FSANZ) for applicable local standards.

The fine bubbles and high acidity of blanc the Blancs cut through the sticky rice and refresh the palate after every bite of sushi. A classic pairing at omakase.

Frequently asked questions about Sushi Rice
How long is cooked sushi rice safe to use?
Cooked sushi rice at room temperature: MAXIMUM 4 hours. This is an HACCP requirement, not a recommendation. Bacillus cereus spores survive cooking and produce a heat-stable toxin at room temperature that causes vomiting. Discard after 4 hours, even if the rice looks and smells fine. Never refrigerate sushi rice: it hardens.
Why won't my nigiri hold its shape?
The most common causes: 1) Rice too cold (below 30°C/86°F): hardens and falls apart. 2) Rice too warm (above 42°C/108°F): too sticky and clings to hands. 3) Too much water when cooking: rice is waterlogged. 4) Not washed enough: excess surface starch makes rice over-sticky. Ideal nigiri rice temperature: 37–38°C (99–100°F). Use tezu (water mixed with rice vinegar) on your hands.
Can I use regular long-grain rice for sushi?
No. Long-grain indica rice (basmati, jasmine) has low amylopectin content and doesn't stick enough for sushi shapes. Nigiri falls apart, maki rolls open up. Use only short-grain japonica varieties: Koshihikari, Calrose, Nishiki. Calrose is the most affordable option with good results.
What is the vinegar, sugar and salt ratio for sumeshi?
Standard per 720g raw rice (yields approx. 1kg cooked): 80ml rice vinegar + 20g sugar + 10g salt. Heat the vinegar mixture until sugar and salt dissolve — do not boil. Add to still-warm rice (60–65°C/140–149°F) and fold using a cutting motion on a wooden hangiri board. Fan the rice for rapid cooling to serving temperature.
At what temperature should you store Sushi Rice?
Store Sushi Rice at Raw: cool and dry. Cooked: 37-40°C (service, max 4h) or cool down immediately <10°C for storage, compliant with EU Regulation 852/2004 and Codex Alimentarius guidelines.
How do you prepare Sushi Rice professionally?
The primary professional technique for Sushi Rice is Sushi-rice boil (precisie-method) at Kookpunt, then 15 min damp on laag heat for Wassen 3-5 min, soaking 30 min, koken 15 min, stomen 10 min. Always verify core temperature with a calibrated probe thermometer.

Milk allergen and lactose intolerance
The EU-14 allergen "Milk (including lactose)" covers two distinct conditions, both of which require declaration: (1) cow's milk allergy, an immunological reaction to milk proteins (casein, whey), and (2) lactose intolerance, an enzymatic deficiency (lactase) preventing digestion of milk sugar. Both groups must be informed separately on the menu. Lactose-free is not the same as milk-protein-free: a guest with cow's milk allergy may still react to lactose-free products.
