The quick answer
Use Japanese-style short- or medium-grain white rice, rinse gently and cook with the water quantity specified for that rice or your cooker’s sushi setting. Fold a measured rice-vinegar seasoning into the warm cooked rice without crushing it. Cool for shaping and do not leave it sitting out for hours.
In this guide
Start with the right rice
Sushi rice describes seasoned cooked rice as well as the grains sold for making it. Japanese-style short- or medium-grain white rice has the useful stickiness for shaped pieces and rolls. Long-grain basmati will not produce the same texture. Glutinous or sweet rice is a different ingredient despite the tempting name.
A rice-cooker cup is often 180 ml, whereas a US measuring cup is about 240 ml. Use the cup and fill markings supplied with the cooker when its instructions require them. Mixing those cup systems changes the water proportion.
Rinse, drain and cook
Measure before washing
Weigh the dry rice or use the cooker’s designated cup. Check the package or appliance directions for the water and any soaking period.
Rinse gently
Cover with cool water, move the grains gently and drain. Repeat until the water is less cloudy. Do not grind grains aggressively or assume the water must become perfectly transparent.
Drain and measure water
Drain as directed so unmeasured rinse water does not accumulate. Add the measured fresh cooking water, or fill to the proper sushi line after the rice is in the cooker.
Cook and rest
Follow the rice’s stovetop method or the appliance’s sushi setting. Keep the lid closed during the specified cook and rest so steam can distribute. Do not compensate for uncertainty by constantly adding water.
Fold in the seasoning without making a paste
A useful small-batch example is 2 tablespoons / 30 ml unseasoned rice vinegar, 2 teaspoons sugar and 1/4 teaspoon fine salt for about 150 g / 5.3 oz dry rice. Dissolve the sugar and salt; adjust to the particular recipe and taste. This is a seasoning example, not a substitute for the rice’s cooking-water directions.
Ready-seasoned sushi vinegar already contains sugar and salt, so follow its label instead of adding the same amounts again. Move warm cooked rice to a broad non-reactive bowl and distribute seasoning gradually with a rice paddle. Fold and separate with a light slicing motion rather than stirring into mush.
Cool for shaping; handle leftovers safely
Let freshly seasoned rice cool until comfortable for shaping. Cover briefly with a clean damp cloth if needed to protect its surface, but prepare rolls promptly. Homemade vinegar seasoning does not establish a tested safe pH for extended room-temperature holding.
Refrigerate leftover rice promptly, ideally within 1 hour, and use within 24 hours; reheat thoroughly only once if serving it hot. Refrigeration makes sushi rice firmer, but that texture tradeoff is preferable to storing it warm for hours. This guide does not establish the safety of raw fish; choose fully cooked fillings when appropriate.
A few useful answers
Can I use seasoned rice vinegar?
Yes, but check its label because sugar and salt are usually already included. Do not automatically add the full seasoning example on top.
Why is my sushi rice mushy?
Common causes include too much water, poorly drained rinse water and aggressive mixing. Check the measured water and fold the cooked grains gently.
Use the full recipe alongside these tips, and follow the stated care and safety limits of your equipment.
