What You’ll Need
Gather these simple ingredients to create your Spicy Tuna Rice Ball:
- 2 cups sushi rice
- 2 1/2 cups water
- 1 cup canned tuna, drained
- 3 tablespoons Kewpie mayo
- 1 tablespoon sriracha (or to taste)
- Salt, to taste
- Roasted seaweed sheets
- Sesame seeds (optional)
- Chopped green onions (optional)
Let’s Make It Together
Rinse the Sushi Rice: Start by rinsing the sushi rice under cold water until the water runs clear. This helps remove excess starch, ensuring fluffy rice. Combine the rice and water in a rice cooker and cook according to the manufacturer’s instructions.
Prepare the Tuna Mixture: While the rice is cooking, mix the drained tuna with Kewpie mayo and sriracha in a bowl. Taste as you go and add salt to your preference—it should be a flavorful contrast to the mild rice.
Cool the Rice: Once the rice is cooked, let it cool slightly. You want it warm but not scalding hot so that handling it is comfortable.
Shape the Rice Balls: Wet your hands to prevent sticking, then take a handful of rice and flatten it in your palm. You want it just thick enough to hold the filling.
Add the Filling: Place a spoonful of the tuna mixture in the center of the rice, then mold the rice around it to form a triangular shape. Press firmly but gently, don’t crush it.
Wrap It Up: Wrap the formed rice ball with a strip of roasted seaweed, which adds a delightful crunch.
Garnish if Desired: Optionally, sprinkle with sesame seeds or chopped green onions for an extra layer of flavor and texture.
Serve and Enjoy: Serve immediately or pack for a snack, picnic, or meal on the go. They also taste great chilled!
Delicious Variations to Try
- Spicy Shrimp Version: Substitute canned tuna with cooked shrimp, and add a splash of lemon juice for a zesty twist.
- Vegetarian Delight: Replace tuna with mashed avocado, cucumber, and a bit of lime juice for a fresh vegetarian option.
- Creamy Cilantro-Jalapeño: Mix in some finely chopped cilantro and jalapeño with the tuna for a more vibrant, southwestern flavor.
- Nutty Sesame Spin: Add toasted sesame oil in the tuna mixture for a rich, nutty flavor that complements the rice beautifully.
