1 Ingredients

Qty Ingredient
2 cups 400 g Short-grain Japanese rice (sushi rice)
2 1/4 cups 540 ml Water
1 tsp 5 g Kosher salt
2 sheets 5 g Nori seaweed sheets
5 oz 140 g Canned tuna (drained)
2 tbsp 30 ml Japanese mayonnaise (Kewpie)
1 tsp 5 ml Soy sauce
1 tbsp 10 g Toasted black or white sesame seeds

2 Method

1

Step 1. Wash the rice in a bowl by swirling it in cold water and draining it 3-4 times until the water runs mostly clear. Let the rice soak for 30 minutes, then drain thoroughly.

2

Step 2. Place the rice and water in a rice cooker and cook according to the 'white rice' setting. If using a pot, bring to a boil, then cover and simmer on low for 12-15 minutes. Let it steam for 10 minutes before fluffing.

3

Step 3. While the rice cooks, prepare the filling by mixing the drained tuna with Japanese mayonnaise and soy sauce in a small bowl.

4

Step 4. Cut the nori sheets into 1-inch strips or small rectangles. Prepare a small bowl of salted water for your hands.

5

Step 5. Wet your hands with the salted water to prevent sticking and to season the rice. Scoop about 1/2 cup of warm rice into your palm.

6

Step 6. Create a small indentation in the center of the rice and place 1-2 teaspoons of the tuna filling inside. Gently fold the rice over the filling to cover it completely.

7

Step 7. Use both hands to press the rice into a triangular shape by cupping one hand to form the base and the other to form the top angle. Press firmly but avoid crushing the grains.

8

Step 8. Wrap a strip of nori around the bottom or the center of the onigiri. Sprinkle with sesame seeds and serve immediately.

💡 Chef's Tips

  • ·

    Use warm rice (not hot or cold) for the best shaping results and to help the nori adhere.

  • ·

    Keep your hands moist with salted water throughout the process to prevent the starch from sticking to your skin.

  • ·

    Use a rice mold if you find hand-shaping difficult for consistent sizes.

  • ·

    Wrap the onigiri in plastic wrap if not eating immediately to prevent the rice from drying out.

? FAQ

Can I use long-grain rice?
No, short-grain Japanese rice is essential because its starch content makes it sticky enough to hold its shape.
What other fillings can I use?
Traditional options include umeboshi (pickled plum), salted salmon, katsuobushi (bonito flakes), or kombu (seaweed).
How long do onigiri stay fresh?
They are best eaten within a few hours, but can be refrigerated for up to 24 hours if wrapped tightly. Note that the rice will harden in the fridge.
Can I freeze onigiri?
Yes, wrap them individually in plastic wrap (without the nori) and freeze. Reheat in the microwave and add fresh nori before eating.
