Ingredients needed 🛒1 servings

  • Tuna 1 can (small)
  • Mayonnaise 3 tbsp
  • Soy sauce 1 tsp
  • Sugar 1 tsp
  • Yellow mustard (or wasabi) 1 tsp
  • Instant rice 1 packet
  • Seaweed flakes as needed

Recipe 🍳

  1. Drain the oil from 1 can of tuna as much as possible (for a thick consistency) and place it in a bowl.
  2. Add 3 tbsp mayonnaise, 1 tsp soy sauce, and 1 tsp sugar to the tuna in that order.
  3. Add about 1 tsp of yellow mustard or wasabi from home.
  4. Mash the tuna completely with a spoon, stirring for a long time until the sauce becomes thick and dense.
  5. Microwave the instant rice for 2 minutes, then spread it flat and wide on a cutting board or large plate using a rice paddle.
  6. Pile the prepared tuna mayo sauce generously in the center of the spread rice.
  7. Flip the rice over to completely envelop the tuna mayo sauce, then press firmly with the rice paddle to shape it.
  8. Once it holds together, use your hands to shape it into a firm, round ball, then coat the outside evenly with seaweed flakes to finish.
  1. Mix tuna, mayonnaise, soy sauce, sugar, and yellow mustard to make a thick sauce.
  2. Spread the heated instant rice wide, place a generous amount of tuna mayo sauce in the center.
  3. Shape firmly into a ball, then coat the outside evenly with seaweed flakes.

Cooking tips 💡

  • When shaping the rice ball, make sure the tuna mayo sauce is mixed to a non-runny, very thick and sticky consistency so it doesn't leak out.
  • Adding a little yellow mustard or wasabi to the mayonnaise base cleans up the greasy taste, preventing it from becoming cloying.
  • If you find rice sticking to your hands messy, wear disposable gloves or use plastic wrap underneath to shape the ball conveniently.
