Onigiri are a classic Japanese snack, the compact rice balls are a staple of the country’s convenience stores. They are portable, flavorful and filling — the ideal travel companion — and include dozens of variations. The technique is simple: The filling of choice (salmon, in this case) gets spooned into balls of rice that are shaped into triangles and wrapped in crispy seaweed. Wetting and salting your hands before working with the rice is key — it seasons the rice and prevents the grains from sticking to your palms.

Preparation

  1. Step 1

    Make the rice: Put the rice in a large bowl, add enough tap water to cover the rice, and wash it, using your hands to swish the grains around. Discard the water. Repeat this process 3 or 4 times. Let the rice soak in water for 30 minutes. Transfer the rice to a sieve, drain and let sit for at least 15 minutes. While the rice is being soaked and drained, heat the oven to 425 degrees.

  2. Step 2

    Combine the rice and 2½ cups water in a medium pot. Cover the pot with a lid and bring to a boil over medium heat. Once the water is boiling, turn the heat down to low and continue to cook, covered, until the water is completely absorbed, 12 to 13 minutes. Take a quick peek, and if you see any water left, cover and continue cooking for another minute or so.

  3. Step 3

    Remove the pot from the heat and let it sit, covered, for another 10 minutes. Uncover and let the rice cool until you can hold the rice without burning your hands. (To cool it quickly, spread it out on a sheet pan). Do not let the rice cool down completely.

  4. Step 4

    Make the filling: Sprinkle a little salt on both sides of the salmon fillet, and place the fillet on a small sheet pan or baking dish. Bake for 10 to 20 minutes, until the salmon flakes easily when you poke it with a fork.

  5. Step 5

    Break the cooked salmon into flakes and set it aside, discarding the skin if there is any (or you can eat it).

  6. Step 6

    While the rice is cooling, cut the nori into 1½-inch-wide strips.

  7. Step 7

    Wet your hands to prevent the rice from sticking to them. Put some salt on your hands by dipping three fingertips in salt and rubbing to spread it all around your palms.

  8. Step 8

    Scoop a handful (about ⅓ cup) of warm rice into one hand. Create a small indentation in the center of the rice. Put 1 to 2 teaspoons of salmon inside. Then mold the rice with your hands around the indentation to cover the filling completely.

  9. Step 9

    Gently form the rice into a triangle, using three fingers (thumb, pointer finger, middle finger) to make a triangle corner. Squeeze and pat the rice just firmly enough so the onigiri doesn’t fall apart. You don’t want to squeeze the rice too tightly.

  10. Step 10

    Wrap the nori around the onigiri like you’re wrapping a blanket around a baby, then sprinkle the top point that’s not wrapped in nori with sesame seeds. You can also wrap the seaweed over the bottom of the onigiri, like a flap or a diaper, and sprinkle sesame seeds along the other two sides. If your hands get too messy, wipe them off and re-dip them in water and salt before you make the next one. Repeat these steps with the rest of the rice, salmon and nori.

  11. Step 11

    Eat the onigiri immediately, as the rice gets hard when you refrigerate it. But if you really need to wait to eat them, there’s a trick: wrap the whole tray of onigiri with thick kitchen towels and store in the fridge. Bring to room temperature before eating.

Here's my kids lunch version: 1. Wake up, wash rice, use short grain if possible, if not, no worries, cook on quick setting in the rice cooker. 2. Find the onigiri mold you bought on Amazon. 3. Cut nori into strips, or whatever fits your mold. Follow directions here about wetting/salting your hands. 4. Find something in the fridge to put in the middle. Smoked salmon and Kewpie? Avocado and cukes? Leftover tuna salad? 5. Put rice, then filling, then rice in mold, wrap in nori. Happy kids!

Mixing furikake with the cooked rice makes for umami-rich onigiri! Especially love furikake made with dried shiso. My husband's favorite Japanese convenience store onigiri is tuna with mayo :).

No, the rice shouldn't be seasoned. For sushi it should, but for onigiri it traditionally is not.

How far in advance can I make these for a picnic?

I would recommend high quality short grain rice such Tamanishiki (grown in Sacramento valley) that is less than a year old after milling. Cook the rice in a Zojirushi rice cooker with the sushi rice setting. Also the salmon can be perfectly cooked in a plastic bag in a sous vide cooker at 131F for 45 minutes.

My family always used the salted water technique Priya describes for food safety. Pickled plums (umeboshi) were often placed inside for the same reason. Then we would eat them with chicken karaage that had been sitting out for hours, so go figure. I don’t know how I survived my childhood.
