How to Make Spicy Tuna Rice Ball
Let’s dive into the cozy process of making these delicious rice balls together! Follow these simple steps for a delightful snack.
Rinse the sushi rice under cold water until the water runs clear. Combine the rice and water in a rice cooker and cook according to the rice cooker instructions. Once done, let it sit for 10 minutes to achieve the perfect texture.
In a bowl, mix the drained tuna with Kewpie mayonnaise, sriracha, and a pinch of salt to taste. Adjust the spice level to suit your palate—don’t be shy if you love a little heat!
Once the rice is cool enough to handle, wet your hands to prevent sticking. Take a small amount of rice and flatten it in your palm, enjoying the delightful, sticky texture.
Place a spoonful of the spicy tuna mixture in the center, then mold the rice around it to form a triangle-shaped ball. Don’t worry if they aren’t perfectly shaped; each one is unique!
Wrap each onigiri with a strip of roasted seaweed. Optionally, sprinkle with sesame seeds or chopped scallions for an extra layer of flavor and texture. Enjoy your homemade spicy tuna rice balls as a snack or a meal!

Chef Emma’s Helpful Tips
To make your rice ball-making experience even smoother, here are a few tips from my own kitchen:
Make-Ahead Advice: These Spicy Tuna Rice Balls can be made ahead and stored in the fridge for 2-3 days. Just wrap them tightly in plastic wrap, and they’ll be ready for a snack attack!
Choosing Sushi Rice: Make sure to use authentic sushi rice for the best texture; it’s stickier compared to other varieties, making it easier to form the rice balls.
Ingredient Swaps: If you don’t have Kewpie mayonnaise, regular mayonnaise will work, but Kewpie adds a unique umami flavor that’s hard to beat!
Slicing Trick: If you enjoy quality time in the kitchen, but want even quicker rice balls, consider using a cookie cutter to shape your rice—this could be a great way to involve kids!
