Ingredients
- 1 piece of nori sheet, cut into 4 equal slices for serving (optional)
- 1 spring onion, finely chopped, for serving (optional)
- 100g cold cooked sushi rice (about 75g uncooked sushi rice)
- 1 teaspoon gochujang
- 1 teaspoon soy sauce
- 1 teaspoon sesame oil
- ½ teaspoon gochugaru flakes
- 1 teaspoon sugar
- ½ teaspoon minced garlic
- ½ teaspoon minced ginger
- 1 teaspoon ketchup
- 125g tin of tuna
- 1 tablespoon mayonnaise
- 1 teaspoon black pepper
- 1 spring onion, finely chopped
Instructions
- Step 1: In a bowl, combine the gochujang, soy sauce, sesame oil, gochugaru flakes, sugar, minced garlic, minced ginger, and ketchup. Add the cold cooked sushi rice and gently mix until every grain is evenly coated with the orange-red sauce.
- Step 2: In another bowl, mix the tuna, mayonnaise, black pepper, and finely chopped spring onion to create the filling.
- Step 3: Lay a large piece of cling film on a clean surface. Place a spoonful of the rice mixture in the center. Add a spoonful of the tuna filling on top of the rice, then cover with another spoonful of rice. Bring the corners of the cling film together and firmly press to shape the onigiri into a compact triangle.
- Step 4: Refrigerate the shaped onigiri for at least 10 minutes to help it hold its form. Repeat the shaping process with the remaining rice and tuna mixture.
- Step 5: Once chilled, wrap each onigiri with a slice of nori around two sides and sprinkle with chopped spring onion. Serve and enjoy!
Tips & Variations
- For extra flavor, add a small piece of pickled radish inside the filling.
- You can substitute tuna with cooked salmon or crab meat for variety.
- If you prefer less heat, reduce or omit the gochugaru flakes.
- Use freshly cooked rice cooled to room temperature if sushi rice is unavailable, but sushi rice gives the best texture.
Storage
Store the onigiri in an airtight container in the refrigerator for up to 24 hours. To enjoy later, eat cold or warm gently in the microwave for about 20 seconds without the nori to keep it crisp.

FAQs
Can I use regular rice instead of sushi rice?
You can use regular short-grain rice, but sushi rice has a firmer, stickier texture that helps the onigiri hold its shape better.
Is it necessary to chill the onigiri before serving?
Refrigerating the onigiri helps it firm up and hold its triangle shape, making it easier to handle and eat.
