Ingredients:

Notes on Rice:

For the best onigiri, using short-grain Japanese rice is highly recommended. Its slightly sticky texture helps the rice balls hold their shape beautifully. If you’re cooking rice specifically for this recipe, ensure it’s cooked according to package directions and then let it cool slightly until it’s warm but not hot to the touch. This makes it easier to handle and shape. If you have leftover cooked short-grain rice, this is the perfect opportunity to use it up! Just make sure it’s properly stored and reheated gently before use.

Preparation and Assembly:

Step 1: Prepare the Tuna Filling

The heart of our onigiri is the savory tuna filling. Begin extract by draining your canned tuna thoroughly. If you’re using tuna packed in oil, drain as much of the oil as possible. If you’re using tuna in water, drain it well. In a small bowl, combine the drained tuna with the Japanese mayonnaise. Mix everything together until the tuna is evenly coated and forms a creamy, cohesive filling. Japanese mayonnaise has a slightly tangier and richer flavor than regular mayonnaise, so if you have access to it, it’s worth the try! However, regular mayonnaise will absolutely work in a pinch and still deliver a delicious result. You can also add a pinch of black pepper to the filling if you like a little extra zing.

Step 2: Season the Rice

Next, we need to prepare the rice. If your cooked rice is still warm, that’s ideal. In a medium bowl, add the cooked short-grain rice. Sprinkle the 1/2 teaspoon of salt evenly over the rice. Gently mix the salt into the rice using a spoon or a rice paddle, being careful not to mash the grains. The salt not only adds flavor but also helps to preserve the onigiri slightly, making it last a bit longer. You want to ensure the salt is distributed evenly throughout the rice for consistent taste in every bite.

Step 3: Shape the Rice Balls

Now comes the fun part – shaping the onigiri! You’ll want to moisten your hands with a little water to prevent the rice from sticking. This is a crucial step for smooth shaping. Take about 1/2 cup of the seasoned rice into your wet hands. Gently cup your hands and begin extract to form a ball. You can also make a traditional triangle shape if you prefer. To do this, flatten the rice slightly in your palm, then press your fingers into the center to create an indentation. Place about a tablespoon of the tuna-mayo mixture into this indentation. Then, carefully bring the edges of the rice up and around the filling, gently pressing to seal it inside. Continue to gently shape and firm the rice ball in your hands, aiming for a compact yet not overly dense shape. Don’t worry if your first few aren’t perfectly shaped; practice makes perfect, and they’ll still taste amazing!

Step 4: Wrap with Nori

The nori seaweed adds a wonderful salty, umami flavor and a satisfying textural contrast to the soft rice. Take one sheet of nori (or half a sheet, as per your preference). If you’re using the full sheet, you can cut it into strips or larger pieces. For a traditional look, wrap a strip of nori around the bottom of the onigiri, or gently press a piece onto one or two sides. If you’re using half a sheet and aiming for a classic look, you can cut it into a triangle or a rectangular strip to wrap around the base. The slight moisture from the rice will help the nori adhere. If you’re in a hurry, you can even crum extractble dried nori into the rice itself during the seasoning step for a more integrated flavor, but the visual appeal of the nori wrap is undeniable.

Step 5: Garnish (Optional)

For an extra touch of flavor and visual appeal, you can sprinkle some sesame seeds onto your onigiri. This is completely optional, but it adds a lovely nutty aroma and a subtle crunch. You can gently press the sesame seeds onto the surface of the rice balls, or sprinkle them on top before or after wrapping with nori. If you’ve cut your nori into strips, you might want to sprinkle the seeds on the exposed rice areas. This final touch elevates your simple onigiri into something a little more special.

And there you have it! Delicious, homemade Japanese Tuna Onigiri ready in just about 15 minutes. These are best enjoyed fresh, but they can be stored at room temperature for a few hours or refrigerated for a day (though the nori may soften in the fridge). Enjoy your quick and satisfying Japanese culinary creation!

Frequently Asked Questions:

Can I make the rice ahead of time for my Japanese Tuna Onigiri?

Absolutely! You can cook your sushi rice a day in advance and store it in an airtight container in the refrigerator. When you’re ready to make your onigiri, gently warm the rice before shaping it. This can save you even more time on the day.

What other fillings can I use besides tuna?

The beauty of onigiri is their versatility! Other popular fillings include flaked salmon, umeboshi (pickled plums), seasoned kombu (kelp), or even finely chopped chicken. Just ensure the filling is well-seasoned and not too wet so it doesn’t make the rice soggy.
