Ingredients:

Get Ready to Make Your Onigiri

First things first, let’s gather our ingredients and get organized. The beauty of this recipe is its simplicity. The most important component is the cooked short-grain rice. If you’re using leftover rice, make sure it’s been properly stored and is at room temperature or slightly warmed. If you’re cooking fresh rice specifically for this recipe, aim for a slightly firmer texture, as mushy rice won’t hold its shape as well. As soon as your rice is ready, spread it out slightly on a plate or in a bowl to help it cool down to a temperature that’s comfortable to handle with your hands. This initial cooling step is crucial for the shaping process.

Prepare the Delicious Tuna Filling

While the rice cools, let’s prepare the star of our onigiri filling: the tuna. Open your can of tuna and drain off any excess liquid. If you’re using tuna packed in oil, this is the preferred choice for a richer flavor and creamier texture, but tuna in water works perfectly fine too. Transfer the drained tuna to a small bowl. Now, add the mayonnaise. Japanese mayonnaise, like Kewpie, has a distinct tangin extractess and creaminess that elevates the filling, but regular mayonnaise is a great substitute if that’s what you have on hand. Mix the tuna and mayonnaise together thoroughly until well combined. You want a moist, cohesive filling that’s easy to scoop and won’t fall apart.

Seasoning the Rice for Perfect Flavor

Once your rice has cooled to a manageable temperature, it’s time to season it. This simple step makes a huge difference in the overall taste of your onigiri. In a separate bowl, place the cooked rice and sprinkle the 1/2 teaspoon of salt evenly over the top. Gently mix the salt into the rice using a spoon or your hands. The goal here is to distribute the salt evenly without mashing the rice grains. You want each grain to be lightly seasoned. A gentle folding motion is best. This salt will bring out the natural sweetness of the rice and provide a subtle savory base for the tuna filling.

Shaping the Onigiri: A Hands-On Delight

Now for the fun part – shaping the onigiri! Wet your hands with a little water and clap them together to remove excess water. This prevents the rice from sticking to your hands. Take about half a cup of the seasoned rice and place it in the palm of one hand. Create a small indentation in the center of the rice. This is where you’ll place your delicious tuna filling. Spoon about 1 to 1.5 tablespoons of the tuna mixture into the indentation. Now, carefully bring the rice around the filling, gently enclosing it. Begin extract to shape the rice into your desired form. The classic onigiri shape is a triangle, but you can also make them into spheres or cylinders. Cup your hands and gently press the rice together, rotating it to form the shape. Don’t press too hard, or the rice will become dense and sticky; aim for a firm but light hold.

Adding the Finishing Touches

Once your onigiri have been shaped, it’s time to add the nori and sesame seeds for that authentic Japanese touch. If you’re using full sheets of nori, you can cut them into strips or squares, depending on how you want to decorate your onigiri. For a traditional look, wrap a strip of nori around the base of your triangular onigiri. This not only looks appealing but also makes them easier to hold. If you prefer less nori, you can use smaller pieces or even just a decorative strip. For an extra touch of flavor and visual appeal, sprinkle the optional sesame seeds over the onigiri, particularly on the nori. This adds a pleasant nutty aroma and a delightful crunch. Repeat the shaping and wrapping process until all your rice and filling are used up.

Frequently Asked Questions:

Can I make the rice ahead of time?

Absolutely! Cooked sushi rice can be stored in the refrigerator for up to two days. Gently reheat it in the microwave or on the stovetop with a splash of water to achieve a fluffy texture before making your onigiri.

What kind of canned tuna is best?

For the best flavor and texture, I recommend using albacore or skipjack tuna packed in oil or water. Draining it well is key to preventing the onigiri from becoming too soggy.

Can I add other ingredients to the tuna filling?

Yes, definitely! Feel free to mix in chopped chives, a little Kewpie mayonnaise, a dash of soy sauce, or even some finely diced cucumber for added texture and flavor. Experiment and find your favorite combination!
