Ingredients

  • 300 g cooked short-grain rice
  • 2 nori sheets
  • 2 pieces tamagoyaki or other cooked filling (teriyaki chicken, tonkatsu, or fully-cooked salmon)
  • 2 large lettuce leaves
  • 1 tbsp soy sauce
  • 1 tbsp rice vinegar
  • 1 tsp sugar
  • salt to taste

Steps

  1. 1. In a bowl, combine the warm cooked rice (at approximately 60°C) with 2 tablespoons of soy sauce, 1 tablespoon of rice vinegar, 1 teaspoon of sugar, and 1/2 teaspoon of salt. Mix gently to season the rice evenly.

  2. 2. Place a nori sheet on a clean surface with the shiny side down. Spread about 150 g of the seasoned rice in the center, leaving about 2 cm of space at the edges.

  3. 3. Layer your chosen cooked filling (tamagoyaki, teriyaki chicken, tonkatsu, or fully-cooked salmon) and a lettuce leaf on top of the rice.

  4. 4. Fold the corners of the nori over the filling to form a square package. Ensure that all corners meet in the center and press gently to secure.

  5. 5. Wrap the onigirazu seam-side down in parchment paper or plastic wrap and let it rest for 2-3 minutes to set.

  6. 6. Using a sharp knife, cut the onigirazu cleanly through the middle to expose the colorful filling.

    Why this works

    The technique behind onigirazu relies on the balance of seasoned warm rice and cooked fillings, creating a cohesive and flavorful 'sandwich'. Using warm rice, ideally around 60°C, helps it to mold better and adhere to the nori, while the resting period of 2-3 minutes allows the nori to soften slightly, making it easier to bite into without tearing. If the nori feels too stiff or the sandwich starts to break apart when cutting, you can briefly microwave it for about 10 seconds to soften the nori. Remember to always use fully-cooked fillings; any raw seafood like salmon must be cooked thoroughly to ensure safety and enhance flavor. The precise measurements and temperatures are crucial for achieving the perfect texture and flavor balance, ensuring that each bite is as delightful as intended. If you find the rice too sticky, adding a little more vinegar can help achieve a better consistency. Overall, this method emphasizes the importance of temperature and timing in creating a delicious onigirazu.
