Rice balls, also known as onigiri in Japanese, are a popular snack or light meal that can be found in many Asian cultures. They are made from cooked rice that is shaped into triangular or oval shapes and often filled with various ingredients such as tuna, salmon, or pickled plum. However, the key to making perfect rice balls lies in the way the rice is cooked. In this article, we will explore the art of cooking rice for rice balls and provide a comprehensive guide on how to achieve the perfect texture and flavor.
Understanding the Importance of Rice Texture
When it comes to cooking rice for rice balls, the texture is crucial. The rice should be sticky and clingy, but not too wet or mushy. This is because the rice needs to hold its shape when molded into a ball, and excess moisture can cause it to fall apart. On the other hand, if the rice is too dry, it will not stick together properly and will be difficult to shape.
To achieve the perfect texture, it’s essential to understand the different types of rice and their characteristics. Japanese short-grain rice, also known as japonica, is the most commonly used rice for making rice balls. This type of rice is high in starch and has a unique texture that is sticky and clingy.
Choosing the Right Type of Rice
When selecting rice for making rice balls, it’s crucial to choose the right type of rice. Japanese short-grain rice is the best option, but other types of short-grain rice can also be used. Here are some factors to consider when choosing rice:
- Grain length: Short-grain rice is best for making rice balls because it is stickier and clingier than long-grain rice.
- Starch content: Rice with high starch content is best for making rice balls because it will be stickier and more clingy.
- Moisture content: Rice with low moisture content is best for making rice balls because it will be easier to shape and hold its shape.
Popular Types of Rice for Making Rice Balls
Here are some popular types of rice that can be used for making rice balls:
- Japanese short-grain rice (japonica)
- Calrose rice

What is the ideal type of rice for making rice balls?
The ideal type of rice for making rice balls is short-grain rice, also known as japonica rice. This type of rice is sticky and clingy, which makes it perfect for forming into balls and holding its shape. Japanese rice varieties such as Koshihikari, Akita Komachi, and Calrose are popular choices for making rice balls.
When choosing a type of rice, look for short-grain rice that is labeled as “sushi rice” or “Japanese rice.” This type of rice is specifically grown and processed to have the right balance of starch and moisture, which is essential for making rice balls. Avoid using long-grain rice, such as jasmine or basmati, as it is too dry and separate, making it difficult to form into balls.
How do I prepare the rice for making rice balls?
To prepare the rice for making rice balls, start by rinsing the rice thoroughly in a fine-mesh sieve until the water runs clear. This helps to remove any impurities and excess starch, which can make the rice sticky and clumpy. Next, combine the rinsed rice with the right amount of water in a medium saucepan. The general ratio is 1 cup of rice to 1 1/4 cups of water.
Bring the water to a boil, then reduce the heat to low and cover the saucepan with a tight-fitting lid. Simmer the rice for about 15-20 minutes, or until all the water has been absorbed and the rice is cooked. Once the rice is cooked, turn off the heat and let it sit, covered, for 5 minutes. This helps the rice to steam and become fluffy and tender.
What is the right consistency for cooked rice for making rice balls?
The right consistency for cooked rice for making rice balls is slightly sticky and clingy, but not too wet or dry. When you press the cooked rice gently with your fingers, it should hold its shape and not crumble or fall apart. If the rice is too wet, it will be difficult to shape into balls, while rice that is too dry will not hold its shape.
To check the consistency of the cooked rice, try forming a small ball with your hands. If the rice holds its shape and doesn’t fall apart, it’s ready to use. If not, you can try adding a small amount of water or rice vinegar to adjust the consistency.
How do I shape the rice into balls?
To shape the rice into balls, start by wetting your hands with water. This helps to prevent the rice from sticking to your hands. Take a small handful of cooked rice and shape it into a ball by applying gentle pressure with your fingers. Make sure to apply even pressure to form a smooth and round ball.
As you shape the rice into balls, try to apply consistent pressure to ensure that the balls are evenly sized and shaped. You can also use a small mold or shape to help form the rice into perfect balls. Once you have shaped the rice into balls, you can serve them as is or fill them with your favorite fillings.
Can I add flavorings or seasonings to the rice for making rice balls?
Yes, you can add flavorings or seasonings to the rice for making rice balls. In fact, many traditional Japanese rice ball recipes include flavorings such as salt, sake, and mirin. You can also add other seasonings such as soy sauce, sesame oil, or grated ginger to give the rice balls extra flavor.
When adding flavorings or seasonings, mix them into the cooked rice while it’s still warm. This helps the flavors to penetrate the rice evenly and prevents the rice from becoming too sticky or clumpy. Be careful not to add too much liquid, as this can make the rice too wet and difficult to shape into balls.
How do I store leftover rice balls?
Leftover rice balls can be stored in an airtight container in the refrigerator for up to 3 days. To store, place the rice balls in a single layer in the container and cover them with plastic wrap or aluminum foil. You can also freeze the rice balls for up to 2 months. To freeze, place the rice balls in a single layer on a baking sheet and put them in the freezer until frozen solid.
Once frozen, transfer the rice balls to an airtight container or freezer bag and store them in the freezer. To reheat, simply microwave the rice balls for a few seconds or steam them over boiling water until warmed through. Note that frozen rice balls may become slightly softer and more prone to breaking, so handle them gently when reheating.
Can I make rice balls ahead of time?
Yes, you can make rice balls ahead of time, but it’s best to shape the rice into balls just before serving. Cooked rice can be prepared ahead of time and stored in the refrigerator for up to a day. However, shaping the rice into balls too far in advance can cause them to become dry and crumbly.
If you need to make rice balls ahead of time, try shaping the rice into balls and then refrigerating them for up to a few hours. You can also freeze the shaped rice balls and reheat them when needed. However, for the best results, it’s best to shape the rice into balls just before serving to ensure they are fresh and flavorful.
