How to Make Rice Sticky for Rice Balls

Making rice sticky for rice balls, also known as onigiri in Japanese cuisine, is crucial in creating these delightful and portable treats. Onigiri are often filled with various ingredients and wrapped in seaweed, making them a popular snack or lunch option. The right level of stickiness in the rice is essential for shaping the rice balls and ensuring they hold their form. This comprehensive guide will explore how to make rice sticky for rice balls, providing step-by-step instructions and tips for success.

Ingredients and Equipment

To make rice sticky for rice balls, you’ll need the following ingredients and equipment:


Japanese short-grain rice (sushi rice): This type of rice is essential for making onigiri due to its natural stickiness when cooked.


Rice cooker or saucepan with a tight-fitting lid.

Rice paddle or wooden spatula.

A bowl of water: For wetting your hands and rice paddle.

Plastic wrap or a clean kitchen towel (optional): For shaping the rice balls.

Step-by-Step Instructions

Follow these step-by-step instructions to make rice sticky for rice balls:

Measure the Rice

Measure the desired amount of Japanese short-grain rice using a measuring cup. Typically, you’ll want to use about 1/2 to 1 cup of uncooked rice per rice ball, depending on your preference for size and the fillings you plan to use.

Rinse the Rice

Place the rice in a fine-mesh strainer or fine sieve.

Rinse the rice under cold running water, gently stirring it with your fingers until it clears. This helps remove excess starch, making the rice overly sticky and gummy.

Drain the rinsed rice thoroughly to remove any excess water.

Cook the Rice

Cook the rinsed rice in a rice cooker or stovetop according to the package instructions or your rice cooker’s settings. Use the appropriate amount of water for the specific type of rice you’re using.

If you’d like, you can add a pinch of salt to the cooking water for seasoning. This step is optional but can enhance the flavor of the rice.

Once the rice is cooked, let it sit in the rice cooker or saucepan with the lid on for 10-15 minutes. This resting period allows the rice to steam and become stickier.

Wet Your Hands

Before handling the rice, wet your hands with a bowl of water. This prevents the rice from sticking to your hands and makes it easier to shape into onigiri.

Season the Rice (Optional)

While the rice is still warm, you can season it with salt and water to enhance the flavor. Combine about 1/4 teaspoon of salt in a small bowl with a few tablespoons of water. Mix until the salt is dissolved.

Sprinkle the salt water mixture evenly over the rice while gently folding it with a rice paddle or wooden spatula. Continue to moisten your hands with water as needed to prevent sticking.

Shape the Rice Balls

To shape the rice into onigiri, wet your hands again. This is essential for preventing the rice from sticking to your hands.

Scoop up a portion of warm, seasoned rice (about the size of your palm for a single rice ball) and place it in one hand.

Use your other hand to gently press and shape the rice into a compact triangle, ball, or cylinder shape. Depending on your preference and filling, you can shape it flat or into a three-dimensional form.

If you’re adding a filling to the center of the rice ball, make an indentation in the center with your thumb and place the filling inside. Then, shape the rice around the filling.

You can use plastic wrap or a clean kitchen towel to help shape the rice balls. Place a piece of plastic wrap or a towel in your hand, add the rice, shape it, and then wrap it tightly to form the onigiri.

Wrap and Serve

If you need to wait to serve the rice balls, wrap them individually in plastic wrap or a clean kitchen towel to prevent them from drying out.

Onigiri can be served plain or wrapped in a strip of seaweed (nori), a common way to enjoy them in Japan. To add nori, wrap it around the rice ball just before eating to keep it crispy.

Enjoy your homemade onigiri as a snack, light meal, or bento box addition.

Tips for Making Sticky Rice Balls

To ensure the rice is sticky enough for shaping rice balls, consider the following tips:

Use Short-Grain Rice: Japanese short-grain rice (sushi rice) is the best choice for onigiri because of its natural stickiness when cooked.

Rinse Thoroughly: Rinse the rice well to remove excess starch, which can result in overly sticky or gummy rice.

Seasoning: Season the rice with some salt and water for extra flavor. This step is optional but enhances the taste.

Moisten Hands: Keep your hands moist while handling the rice to prevent sticking.

Shape When Warm: Shape the rice balls while the rice is still warm, as it’s more pliable at this stage.

Experiment with Fillings: Get creative with your onigiri fillings. Popular options include pickled plums (umeboshi), salmon, tuna, and seasoned vegetables.

Wrap in Nori: To keep the nori crisp, wrap it around the rice ball just before eating.

Making sticky rice for rice balls, or onigiri is a delightful culinary endeavor that allows you to explore different shapes, fillings, and flavors. Once you’ve mastered the art of sticky rice, you can create a variety of delicious onigiri to enjoy as a snack or meal on the go. Happy cooking!
