Ingredients:
- 500g (2 1/2 cups) short-grain sushi rice
- 600ml (2 1/2 cups) water
- 1 tin (150g/5 oz) tuna in olive oil, drained
- 45g (3 tbsp) mayonnaise
- 5g (1 tsp) soy sauce
- Sea salt, to taste
- Sheets of nori (seaweed), cut into strips
- Roasted sesame seeds (optional), for garnish
Instructions:
Step 1: Prepare the Rice
Rinse the sushi rice under cold water until the water runs clear. This removes excess starch and prevents the rice from becoming too sticky. Combine the rice and 600ml (2 1/2 cups) of water in a rice cooker or heavy-bottomed pot. Cook according to the rice cooker instructions or bring to a boil, then reduce to a simmer, covering the pot, and cook for 15 minutes. Let it stand for another 10 minutes, covered, to ensure thorough steaming.
Step 2: Prepare the Tuna Filling
In a mixing bowl, combine the drained tuna with mayonnaise and soy sauce. Mix well until the ingredients are evenly distributed. Adjust the seasoning with a pinch of sea salt if needed, to balance the flavors to your preference.
Step 3: Shape the Onigiri
Once the rice has cooled enough to handle, wet your clean hands or line a cupcake pan with plastic wrap. Take about 80g (2/3 cup) of rice and shape it into a flat circle. Place a teaspoon of the tuna filling in the middle, then mold the rice around it, forming a ball or triangle. Secure the shape using a bamboo mat, if desired, to achieve a more traditional form. Repeat with the remaining rice and filling.
Step 4: Assemble and Finish
Wrap each onigiri with a strip of nori, leaving part of the rice exposed. Garnish with roasted sesame seeds if you prefer an added crunch and nutty flavor. The nori sheet helps to hold the onigiri together and provides a delightful texture contrast.
Conclusion: Onigiri with tuna filling offers a perfect blend of simplicity and flavor, making it a delightful treat that caters to diverse palates. These rice balls are not only a testament to minimalism in Japanese cuisine but also a celebration of flavor harmony. They are perfect for lunchboxes, snacks, or even as a unique serving at gatherings. As you delve into the art of onigiri making, feel encouraged to experiment with other fillings and shapes. Let this foundational recipe be your gateway to a versatile and fun culinary experience.
