🥗 Ingredients
The Rice Base
- 2 cups Short-grain Japanese rice (specifically labeled as sushi rice or Koshikari)
- 2.2 cups Water (filtered water is preferred for cleaner flavor)
- 1 teaspoon Kosher salt (for seasoning the hands during shaping)
The Fillings
- 1 can Canned tuna (drained well, 5oz size)
- 2 tablespoons Japanese mayonnaise (Kewpie brand is highly recommended)
- 1/2 teaspoon Soy sauce (to season the tuna)
- 1 fillet Salted Salmon (Shiozake) (grilled and flaked into small pieces)
- 2-3 pieces Umeboshi (pickled plums, pitted and mashed into a paste)
The Wrappings and Toppings
- 2-3 sheets Nori seaweed (cut into 1-inch or 3-inch strips)
- 2 tablespoons Furikake (Japanese rice seasoning for coating)
- 1 tablespoon Toasted white sesame seeds (for garnish)
- 1 tablespoon Black sesame seeds (for garnish)
👨🍳 Instructions
-
1
Rinse the short-grain rice in a bowl under cold running water, swishing with your hand. Drain and repeat 3-4 times until the water runs mostly clear. This removes excess surface starch for the perfect texture.
-
2
Transfer the rinsed rice to a heavy-bottomed pot or rice cooker. Add 2.2 cups of water and let the rice soak for at least 30 minutes. This ensures the core of each grain hydrates properly.
-
3
If using a pot, bring to a boil over medium-high heat. Once boiling, turn the heat to low, cover tightly, and simmer for 12-15 minutes. If using a rice cooker, simply start the 'white rice' cycle.
-
4
Once the rice is cooked, remove from heat and let it sit, covered, for another 10 minutes to steam. Fluff gently with a rice paddle (shamoji) using a cutting motion to avoid mashing the grains.
-
5
Prepare the fillings: In a small bowl, mix the drained tuna with Kewpie mayo and soy sauce. In another bowl, flake your grilled salmon. Have your umeboshi paste ready.
-
6
Set up a 'shaping station' with a bowl of water (for wetting hands), a small dish of salt, your fillings, and the warm rice.
-
7
Wet both hands with water to prevent sticking. Rub a pinch of salt between your palms; this seasons the rice and helps preserve the onigiri.
-
8
Scoop about 1/2 cup of warm rice into one hand. Create a small indentation in the center of the rice mound.
-
9
Place 1-2 teaspoons of your desired filling into the indentation. Gently fold the rice over the filling to enclose it completely.
-
10
Cup your hands to form a triangle shape. Press firmly but gently—you want the rice to hold together without being crushed. Rotate the ball three times to sharpen the corners.
-
11
Wrap a strip of nori around the bottom or the entirety of the onigiri. The moisture from the rice will help the seaweed adhere.
-
12
Optional: Dip the edges of the rice ball in furikake or sesame seeds for extra flavor and a beautiful presentation.
-
13
Repeat the process with the remaining rice and fillings. Serve immediately for crispy nori, or wrap in plastic wrap for a portable snack.
💡 Chef's Tips
Always use warm rice; cold rice will not stick together and the balls will fall apart. Don't overfill the centers, or the rice ball will crack and leak during the shaping process. If you struggle with hand-shaping, you can use plastic wrap or an onigiri mold to achieve a perfect triangle. For a crispy variation (Yaki Onigiri), brush the finished balls with soy sauce and grill them in a pan with a little sesame oil. Keep your hands damp throughout the process; if they get too dry, the starch will stick to your skin instead of the other rice grains.
🍽️ Serving Suggestions
