Cooking Instructions

The beauty of onigiri lies in its simplicity. We’re not really “cooking” in the traditional sense, but rather assembling delicious components into perfectly portable rice balls.

1.

Prepare the Tuna Filling

This is where the flavor really starts to build! Open your can of tuna and drain off any excess liquid. If you’re using tuna packed in oil, draining is especially important to avoid an overly greasy filling. Transfer the drained tuna to a small bowl. Add the Japanese mayonnaise (or your regular mayonnaise). Japanese mayonnaise, like Kewpie, has a richer, tangier flavor profile that’s fantastic in onigiri, but regular mayonnaise will work perfectly well too. Mix the tuna and mayonnaise together until well combined. You want a creamy, spreadable mixture. You can add a tiny pinch of black pepper if you like, but it’s not essential. Taste it and adjust the mayonnaise if needed. The consistency should be moist but not runny.

2.

Season the Rice

While the tuna mixture is resting, let’s get our rice ready. If you’re using freshly cooked short grain rice, ensure it’s still warm but not scalding hot. Warm rice is much easier to mold. If your rice has cooled down, you can gently warm it in the microwave for about 30-60 seconds. In a separate small bowl, mix the 1/2 teaspoon of salt with about 2 tablespoons of warm water. This helps distribute the salt evenly throughout the rice. Gently pour this salt water over the cooked rice. Using a rice paddle or a spatula, carefully fold the salt water into the rice. The goal here is to evenly season every grain without mashing the rice. You want to coat the rice grains with the salt, not stir vigorously.

3.

Assemble the Onigiri

Now for the fun part: shaping! It’s helpful to have a small bowl of water and a little extra salt (about 1/4 tsp) nearby for your hands. Wet your hands thoroughly with water and then sprinkle a little salt onto your palms. This prevents the rice from sticking to your hands and adds a little extra seasoning to the exterior of the onigiri. Take about 1/2 cup of the seasoned rice and place it in the palm of your hand. Create a slight indentation in the center of the rice with your thumb. This indentation is where we’ll place our delicious tuna filling.

4.

Fill and Shape

Spoon about 1 to 1.5 tablespoons of the tuna mayonnaise mixture into the indentation you made in the rice. Don’t overfill, or it will be difficult to seal. Now, gently gather the edges of the rice around the filling, carefully enclosing it completely. Begin extract to gently pat and shape the rice into your desired form. The most traditional shapes are a triangle or a ball. For a triangle, cup your hands to form a flat base, then use your fingers and the palm of your other hand to form the other two sides, creating a sturdy triangle. If you prefer a ball, simply cup your hands and gently roll the rice until it forms a compact sphere. The key is to apply even pressure so the onigiri holds its shape without becoming too dense or hard. If the rice starts sticking, re-wet your hands and add a touch more salt.

5.

Add the Nori (Optional but Recommended!)

This step is what elevates your onigiri from simple rice balls to classic Japanese snacks. If you’re using whole sheets of nori, you can cut them into strips about 1 inch wide and 3-4 inches long. These are perfect for wrapping around the base of a triangular onigiri or for partially encasing a round one. Gently press the nori strip onto the onigiri. The moisture from the rice will help it adhere. If you prefer less nori, simply use a smaller piece or a half sheet, tearing it to fit your onigiri. For an extra touch of flavor and visual appeal, you can sprinkle the top of your onigiri with the sesame seeds. This is entirely optional but adds a nice nutty aroma and a bit of texture.

Frequently Asked Questions:

Can I use different types of rice?

While short-grain Japanese rice is ideal for its stickiness and texture, you can experiment with other short-grain or medium-grain white rice. Just be sure to adjust the water ratio slightly as needed to achieve a good, moldable consistency.

What if I don’t have mayonnaise?

No worries! You can substitute the mayonnaise with a little bit of Japanese kewpie mayo if you have it, or even plain yogurt mixed with a touch of soy sauce and a pinch of black pepper for a creamier, tangy alternative.

How should I store leftover onigiri?

Onigiri are best enjoyed fresh, but if you have leftovers, wrap them tightly in plastic wrap or an airtight container. They can be stored in the refrigerator for up to a day. Reheat them gently in a microwave or a lightly oiled pan until warmed through.
