Ingredients for Tuna Onigiri
- 2 cups short-grain sushi rice
- 2 1/2 cups water
- 1 can (5 oz) tuna, drained
- 2 tablespoons mayonnaise
- 1 tablespoon soy sauce
- 1 teaspoon rice vinegar
- Salt to taste
- Nori sheets (seaweed), cut into strips
Ingredient Notes and Substitutions
- Sushi rice: This rice gives the right stickiness. You can use short-grain brown rice for a healthier option.
- Tuna: Canned tuna is convenient. Substitute with cooked salmon or chicken for a different flavor.
- Mayonnaise: It adds creaminess. Use Greek yogurt for a lighter alternative.
- Rice vinegar: Balances flavors. Apple cider vinegar works as a substitute.
How to Make Tuna Onigiri
Step 1: Rinse the Rice
Start by rinsing the sushi rice under cold water until the water runs clear. This removes excess starch, ensuring fluffy rice.
Step 2: Cook the Rice
Combine the rinsed rice and water in your rice cooker or pot. Cook according to your rice cooker’s instructions or bring to a boil, then simmer on low for about 18 minutes.
Step 3: Prepare the Filling
In a bowl, mix the drained tuna with mayonnaise, soy sauce, and rice vinegar. This creates a creamy, flavorful filling for your onigiri.
Step 4: Season the Rice
Once the rice is cooked, let it cool slightly. Add salt to taste and mix gently to season the rice evenly.
Step 5: Shape the Onigiri
Lay a piece of plastic wrap on your work surface. Scoop a portion of rice (about a handful) onto the wrap, making a small indentation in the center.
Step 6: Add the Filling
Place a spoonful of the tuna mixture into the indentation. This adds a burst of flavor to every bite.
Step 7: Mold the Rice
Wrap the plastic around the rice and press firmly to form a triangle shape. This helps the onigiri hold together while also giving it a nice appearance.
Step 8: Garnish and Serve
Unwrap the onigiri and wrap a strip of nori around each rice ball. This not only adds flavor but also makes them easy to hold.
Pro Tip: Make sure to wet your hands with water when handling the rice to prevent it from sticking to your fingers.
Tips for the Best Tuna Onigiri
- Use fresh sushi rice for the best texture.
- Experiment with different fillings like avocado or pickled vegetables.
- Keep the rice covered with a damp cloth to prevent it from drying out.
- Make a larger batch and refrigerate for easy meals throughout the week.
- Serve with soy sauce and pickled ginger for added flavor.
Common Mistakes to Avoid
- Skipping the rinsing step can lead to gummy rice.
- Not letting the rice cool slightly can make shaping difficult.
- Overfilling the onigiri can cause them to break apart.
- Using long-grain rice will result in a different texture.
