Onigiri, those triangular-shaped Japanese rice balls, are a staple in many households. They’re easy to make, fun to eat, and can be filled with a variety of ingredients. But have you ever wondered if you can use regular rice instead of sushi rice, or if you can refrigerate or freeze tuna mayonnaise onigiri? In this comprehensive guide, we’ll delve into the world of onigiri and explore the different ways you can make them. From the basics of choosing the right rice to advanced techniques for shaping and filling, we’ll cover it all. By the end of this article, you’ll be an onigiri expert, ready to create your own delicious variations.
Onigiri are a great snack or lunch option, and they’re perfect for taking on the go. They’re also a great way to use up leftover rice and other ingredients. But to make great onigiri, you need to start with the right foundation: Japanese short-grain rice. This type of rice is stickier and clingier than regular long-grain rice, which makes it perfect for holding together in a ball or triangle shape. But what if you don’t have Japanese short-grain rice? Can you use regular rice instead?
The answer is yes, but with some caveats. While regular rice can be used to make onigiri, it won’t hold together as well as Japanese short-grain rice. This is because regular rice is drier and less sticky, which makes it more prone to falling apart. However, if you’re in a pinch and don’t have Japanese short-grain rice, you can still make onigiri with regular rice. Just be sure to adjust the amount of water you use when cooking the rice, and be gentle when handling the onigiri to avoid breaking them apart.

The Importance of Rice
When it comes to making onigiri, the type of rice you use is crucial. Japanese short-grain rice is the best type of rice to use because it’s stickier and clingier than regular long-grain rice. This makes it perfect for holding together in a ball or triangle shape. To prepare the rice, rinse it thoroughly and cook it according to the package instructions. Once the rice is cooked, allow it to cool down to room temperature. This is an important step, as hot rice is too sticky and difficult to work with.
Once the rice has cooled, you can start shaping it into onigiri. To do this, wet your hands with water and take a small handful of rice. Shape the rice into a triangle or ball, depending on your desired shape. You can also use a mold to help you shape the onigiri. If you’re using a filling, such as tuna mayonnaise, place it in the center of the rice and fold the rice over to enclose it.
The type of rice you use can also affect the flavor and texture of the onigiri. Japanese short-grain rice has a naturally sweet flavor and a soft, fluffy texture. Regular long-grain rice, on the other hand, has a drier and more neutral flavor. If you’re using regular rice, you may need to adjust the amount of water you use when cooking it to get the right consistency.
Refrigerating and Freezing Onigiri
Onigiri can be refrigerated or frozen to extend their shelf life. However, it’s generally not recommended to freeze onigiri, especially if they’re filled with tuna mayonnaise. This is because the mayonnaise can separate and become watery when thawed, which can affect the texture and flavor of the onigiri. Refrigerating onigiri, on the other hand, is a great way to keep them fresh for up to a day.
To refrigerate onigiri, simply place them in an airtight container and store them in the refrigerator. You can also wrap them individually in plastic wrap or aluminum foil to prevent them from drying out. If you’re refrigerating onigiri that are filled with tuna mayonnaise, be sure to consume them within a day. This is because the mayonnaise can spoil quickly, especially if it’s not stored properly.
If you need to store onigiri for a longer period of time, you can consider freezing them without the filling. Simply shape the onigiri into their desired shape and place them on a baking sheet lined with parchment paper. Put the baking sheet in the freezer and allow the onigiri to freeze for about 30 minutes. Once they’re frozen, you can transfer them to an airtight container or freezer bag and store them in the freezer for up to 3 months.
Adding Other Ingredients to the Tuna Mayonnaise Mixture
The tuna mayonnaise mixture is a classic filling for onigiri, but you can also add other ingredients to give it extra flavor. Some ideas include diced onions, grated carrot, or chopped green onions. You can also add a squeeze of fresh lemon juice or a sprinkle of soy sauce to give the mixture a bit of zing.
To add other ingredients to the tuna mayonnaise mixture, simply mix them in with the tuna and mayonnaise. Be sure to taste the mixture as you go and adjust the seasoning accordingly. You can also experiment with different types of mayonnaise, such as spicy mayonnaise or wasabi mayonnaise, to give the mixture an extra kick.
In addition to adding other ingredients to the tuna mayonnaise mixture, you can also experiment with different types of fillings altogether. Some ideas include pickled plum, salmon, or boiled egg. You can also use different types of meat or seafood, such as chicken or shrimp, to create a more substantial filling.
Making Onigiri in Advance
Onigiri can be made in advance and stored in the refrigerator for up to a day. This is convenient if you want to make a batch of onigiri for a party or event. To make onigiri in advance, simply shape the rice into its desired shape and place it in an airtight container. You can also add a filling, such as tuna mayonnaise, and store it in the refrigerator until you’re ready to serve.
When making onigiri in advance, it’s a good idea to use short-grain Japanese rice that’s specifically labeled as ‘sushi rice’. This type of rice is stickier and clingier than regular short-grain rice, which makes it perfect for holding together in a ball or triangle shape. You can also add a small amount of rice vinegar to the rice to help preserve it and give it a more authentic flavor.
If you’re making onigiri in advance, be sure to store them in an airtight container to keep them fresh. You can also wrap them individually in plastic wrap or aluminum foil to prevent them from drying out. Onigiri are best served at room temperature, so be sure to take them out of the refrigerator about 30 minutes before serving.
Shaping Onigiri into Different Shapes
Onigiri can be shaped into a variety of different shapes, from triangles to balls to cylinders. The shape you choose will depend on your personal preference and the occasion. For example, triangular onigiri are great for serving at parties or events, while ball-shaped onigiri are perfect for snacking on the go.
To shape onigiri into different shapes, you can use a mold or your hands. If you’re using a mold, simply press the rice into the mold and shape it into its desired shape. If you’re using your hands, wet them with water and take a small handful of rice. Shape the rice into its desired shape, using gentle pressure to mold it into place.
In addition to shaping onigiri into different shapes, you can also experiment with different sizes. For example, you can make small onigiri that are perfect for snacking, or larger onigiri that are great for serving as a meal. You can also add different toppings or fillings to give the onigiri extra flavor and texture.
Using Fresh Tuna Instead of Canned Tuna
While canned tuna is a convenient and affordable option for making onigiri, you can also use fresh tuna for a more premium flavor. Fresh tuna is richer and more flavorful than canned tuna, and it’s perfect for making onigiri that are truly special.
To use fresh tuna, simply chop it into small pieces and mix it with mayonnaise and other ingredients. You can also add other ingredients, such as diced onions or grated carrot, to give the mixture extra flavor. Be sure to handle the fresh tuna safely and store it in the refrigerator at a temperature of 40°F (4°C) or below.
When using fresh tuna, it’s a good idea to choose a type of tuna that’s low in mercury, such as skipjack or albacore. You can also experiment with different types of fish or seafood, such as salmon or shrimp, to create a more varied and interesting filling.
