What is Sushi Rice Water Ratio

Sushi rice, the cornerstone of exquisite sushi dishes, requires precise cooking to achieve the ideal texture and consistency. Central to this process is understanding the sushi rice water ratio – the relationship between the amount of rice and water used during cooking. Mastering this ratio is essential for creating sushi rice that is neither too dry nor too sticky, ensuring the success of your sushi endeavours. In this guide, we’ll delve into the art of sushi rice water ratios, demystifying the science behind it and providing practical insights to help you cook perfect sushi rice every time.

Importance of the Sushi Rice Water Ratio

The sushi rice water ratio is the key to the right balance between fully cooked grains and proper stickiness, making the rice easily shaped into sushi rolls. The ratio directly affects the rice’s texture, moisture content, and quality. Using the correct ratio ensures that the rice absorbs the right amount of water for proper cooking without becoming mushy or dry.

Basic Sushi Rice Water Ratio

The typical sushi rice water ratio is 1:1.1 to 1:1.2, meaning you’ll use slightly more water than rice. This ratio ensures that the rice cooks to the desired level of stickiness while remaining separate and fluffy. For instance, if you’re using 1 cup of rice, you would use about 1.1 to 1.2 cups of water.


Rinsing the Rice

    • Begin by measuring the desired amount of sushi rice you wish to cook.
    • Rinse the rice under cold water in a fine-mesh strainer, gently agitating it with your fingers to remove excess starch. Rinse until the water runs clear.

Measuring Water

    • Use a measuring cup to add the appropriate amount of water based on the sushi rice water ratio. If you’re using 1 cup of rice, pour 1.1 to 1.2 cups of water into a saucepan.

Cooking Process:

    • Place the rinsed rice and measured water in a saucepan and bring them to a boil.
    • Once boiling, reduce the heat to low, cover the saucepan with a tight-fitting lid, and let the rice simmer for 15-20 minutes. This cooking time allows the rice to absorb the water and cook thoroughly.

Resting Time

    • After the cooking time is up, turn off the heat and let the rice sit, covered, for an additional 10 minutes. This resting period allows the rice to steam and become perfectly tender.

Fluffing and Cooling

    • Once the resting time is over, use a rice paddle or fork to fluff the rice gently. This helps release excess steam and prevent the rice from becoming overly sticky.

Tips and Considerations

  • Rice Type: Short-grain Japanese rice is the preferred choice for sushi due to its starch content, contributing to the desired stickiness.
  • Cooking Methods: The water ratio remains consistent whether you’re using a rice cooker, stovetop, or microwave to cook the rice.
  • Altitude and Variations: Altitude and personal preference can influence the ideal water ratio. Experiment with small batches until you find the ratio that suits your taste and cooking environment.


The sushi rice water ratio is fundamental in crafting perfect sushi rice. By understanding this ratio and following the precise cooking instructions, you’ll achieve rice that’s tender, separate, and just the right amount of sticky – the essential qualities of sushi rice. Experimenting with ratios and consistently adjusting for factors such as rice type and altitude will allow you to fine-tune your rice cooking skills. With this knowledge, you’re ready to embark on a journey of creating delectable sushi and other rice-based dishes with the confidence of achieving impeccable results.


What’s the recommended water-to-rice ratio for sushi rice?

The general sushi rice water ratio guideline is 1:1.1 to 1:1.2, meaning slightly more water than rice. For instance, if using 1 cup of rice, add about 1.1 to 1.2 cups of water. This ratio ensures the rice balances stickiness and fluffiness, which is crucial for shaping sushi rolls. It’s a key factor in achieving perfectly cooked and textured sushi rice. Remember, factors like rice type and personal preference might influence the ratio slightly, so feel free to adjust and experiment as needed.

Should I use the same water ratio for different rice types in sushi?

The water ratio can vary slightly based on rice types. While the 1:1.1 to 1:1.2 ratio generally works well for short-grain Japanese rice, which is ideal for sushi, you might need to adjust slightly for other rice varieties. Long-grain rice, for instance, might require a bit more water to achieve the desired texture. It’s a good practice to start with the recommended ratio, observe the rice’s cooking behavior, and make subtle adaptations if necessary. Over time, you’ll develop a sense of how different rice types respond to varying water ratios, ensuring consistently well-cooked rice.

Should I change the sushi rice water ratio based on my altitude?

Yes, altitude can impact the cooking process. Water boils at a lower temperature at higher altitudes, affecting how rice cooks. To compensate, you might need to use a slightly higher water ratio. Experiment by increasing the water amount slightly within the recommended range (1:1.1 to 1:1.2) and monitor the rice’s texture. Adjust as needed to achieve the desired results. Adapting the water ratio based on altitude ensures your sushi rice cooks perfectly, regardless of location.
