Onigirazu: The Flat Onigiri That’s Better Than a Sandwich

Onigirazu: The Flat Onigiri That’s Better Than a Sandwich

Onigirazu, the flat onigiri, is a dish that has been gaining popularity worldwide for its unique twist on traditional Japanese triangular onigiri. What makes this dish special is its ability to balance flavors and textures in a single, compact package. However, many people get it wrong by overcomplicating the filling and neglecting the importance of the right rice texture.

The key technique behind onigirazu lies in the preparation of the sushi rice and the balance of flavors in the filling. It requires a deep understanding of how to cook Japanese short-grain rice to the perfect texture and how to select fillings that complement each other. The philosophy is simple: harmony and balance in every bite.

To make onigirazu, you will need Japanese short-grain rice, water, rice vinegar, sugar, salt, and your choice of fillings such as salmon, pickled plum, and cucumber. The quality of the ingredients and the attention to detail in preparation are what set a great onigirazu apart from a mediocre one.

While it may seem simple, the art of making onigirazu is nuanced and requires practice to master. The full recipe below covers exact weights, step-by-step technique, and the pro details that make the difference.

Full Premium Recipe

Ingredients:

• 400g Japanese short-grain rice
• 540ml water
• 40g rice vinegar
• 10g sugar
• 5g salt
• 120g smoked salmon, sliced
• 60g pickled plum, sliced
• 40g cucumber, thinly sliced

Step-by-Step Instructions:

1. Rinse the rice thoroughly and cook it according to the package instructions. Typically, Japanese short-grain rice is cooked with a 1.35:1 water-to-rice ratio. Bring the water to a boil at 100°C (212°F), add the rice, cover, reduce the heat to low at 60°C (140°F), and simmer for 18 minutes. Then, turn off the heat and let it steam for 5 minutes.

2. While the rice is cooking, prepare the seasoning mixture by combining rice vinegar, sugar, and salt in a saucepan. Heat the mixture over low heat at 60°C (140°F), stirring until the sugar and salt are dissolved. Let it cool to room temperature.

3. Once the rice is done, transfer it to a large bowl and pour the seasoning mixture over it. Gently fold the rice with a wooden spoon to combine, being careful not to mash the grains. Let the rice cool to room temperature.

4. Prepare your fillings by slicing them into thin pieces. For the smoked salmon, slice it into thin strips. For the pickled plum, slice it into thin wedges. For the cucumber, slice it into thin rounds.

5. To assemble the onigirazu, lay a sheet of nori flat on a cutting board. Spread a thin layer of sushi rice onto the nori, leaving a 1-inch border at the top. Arrange your fillings in the middle of the rice. Add another thin layer of sushi rice on top of the fillings, making sure to cover them completely. Fold the bottom edge of the nori up over the filling, then fold in the sides and roll the onigirazu away from you to form a compact rectangle. Repeat with the remaining ingredients.

Pro Tips:

• Use short-grain Japanese rice, as it is stickier and better suited for onigirazu than other types of rice.
• Handle the rice gently when mixing it with the seasoning and when assembling the onigirazu to avoid mashing the grains.
• Experiment with different fillings to find your favorite combinations, but remember to balance flavors and textures.

Common Mistakes to Avoid:

• Overmixing the rice, which can make it sticky and clumpy.
• Using too much filling, which can make the onigirazu difficult to close and can throw off the balance of flavors.

Storage and Reheating Notes:

Onigirazu can be stored in an airtight container in the refrigerator for up to a day. To reheat, wrap it in a damp paper towel and microwave for 20-30 seconds at 600W. Let it cool before serving.
