Why 'Grilled' Rice Balls? 3 Irresistible Charms
- The Ultimate Textural Contrast: Grilling the rice gently in a pan creates a Maillard reaction, yielding a nutty, crispy exterior. Meanwhile, the tuna mayo inside remains incredibly moist and creamy. The combination of these two textures in one bite is heavenly.
- Sweet and Savory Flavor Explosion: Traditional Japanese Yaki Onigiri uses Tsuyu and various seasonings, but this recipe uses basic pantry staples to create an equally luxurious, sticky, sweet, and savory glaze.
- The Best Way to Use Leftovers: Got some leftover cooked rice and a forgotten can of tuna in the pantry? That's all you need to create a fantastic meal or a great pairing with drinks.

Essential Ingredients for Perfect Flavor
[Main Ingredients]
- Cooked Rice (1.5 bowls): Slightly firm rice works best for grilling. If using instant microwave rice, heat it and let it cool slightly.
- Canned Tuna (1 can, approx. 100g-150g): The star of the filling.
- Mayonnaise (to taste): Adds creaminess and binds the tuna.
- Cooking Oil (a little): For greasing the pan.
[Special Soy Glaze Ingredients]
- Soy Sauce (3 tablespoons): Provides the savory, umami base.
- Mirin (3 tablespoons): Adds subtle sweetness and balances the saltiness.
- Oligosaccharide or Corn Syrup (2 tablespoons): Gives the glaze a beautiful shine and helps it caramelize on the rice.
- Water (5 tablespoons): Prevents the sauce from burning too quickly and adjusts the consistency.

Step-by-Step Guide to Crispy Perfection
Step 1: Prepare the Tuna Mayo Filling
The most crucial tip here is to drain the oil from the tuna completely. If the tuna is too wet, the rice ball will become soggy and fall apart during grilling. Press the tuna in a sieve to remove as much liquid as possible. Mix the drained tuna with mayonnaise. Adding a pinch of black pepper here elevates the flavor significantly.
Step 2: Simmer the Special Glaze
In a small pan, combine 3 tbsp soy sauce, 3 tbsp mirin, 2 tbsp oligosaccharide, and 5 tbsp water. Heat over low heat. Sugary sauces can burn in an instant on high heat, so patience is key. Stir gently as it begins to bubble.
Step 3: Achieve the Right Sauce Consistency
Watch the pan closely. The water will evaporate, and the bubbles will become larger. When the sauce thickens slightly to a syrup-like consistency—where dragging a spatula leaves a brief trail—turn off the heat immediately. This glaze is the magic that will seep into the rice grains.
Step 4: Shape the Rice Balls
It's time to assemble! To prevent the rice from sticking to your hands, lightly wet them with water or rub a tiny drop of sesame oil on food-safe gloves. Better yet, use plastic wrap for easy, hygienic shaping.
Flatten a portion of rice in your palm, make a small well in the center, and add a generous scoop of the tuna mayo. Cover it with more rice, ensuring no filling is exposed. Press firmly with both hands to form a tight triangle. Pressing firmly is essential so they don't break in the pan.
Step 5: Grill and Glaze
Lightly oil a wide frying pan and preheat on low heat. Place the firm rice balls in the pan and sear both sides briefly to set the shape.
Next, using a basting brush or a spoon, generously apply the special glaze to the top side. Flip the rice ball and brush the other side. Keep the heat low and continue flipping and brushing until the surface is caramelized, deep brown, and smells incredibly savory. Your crispy, creamy grilled tuna rice balls are ready!

Food Editor's Pro Tips
- Want a spicy kick? Add finely chopped jalapeños or mix a little Sriracha into the mayo. It cuts through the richness and makes it an amazing snack with beer.
- Craving extra crispiness? Melt a small pat of butter in the pan when grilling. The buttery aroma will permeate the rice, making the crust even more irresistible.
