Ingredients:

  • 2 US cups (400g) Japanese Short-Grain Rice (Koshihikari or Nishiki recommended)
  • Cold Water (as needed for washing)
  • 2 US cups (480ml) Filtered Cold Water (for cooking)
  • 1/2 cup (120ml) Unseasoned Rice Vinegar
  • 1/4 cup (50g) Granulated Sugar
  • 1 tsp (5g) Fine Sea Salt

Instructions:

  1. Place the measured rice in a large bowl. Cover with cold water. Gently swirl and rub the grains with your hand. Pour out the milky water. Repeat this process until the water runs almost completely clear (5 to 7 changes). This removes excess starch.
  2. Drain the rinsed rice thoroughly using a sieve. Transfer the rice to the inner pot of the rice cooker. Add the measured 2 cups (480 ml) of cold, filtered water. Let the rice soak in the water for a mandatory 30 minutes to ensure even hydration.
  3. Set the rice cooker to the 'White Rice' or 'Sushi Rice' setting and start the cycle. Do not open the lid during cooking.
  4. Once the cooker finishes its cycle (switches to 'Keep Warm'), allow the rice to rest, undisturbed, for 10 minutes. This mandatory rest allows the steam to fully redistribute and complete the cooking.
  5. While the rice is resting, combine the rice vinegar, sugar, and salt in the small saucepan. Heat the mixture gently over medium-low heat, stirring constantly, until the sugar and salt are completely dissolved. Remove immediately and set aside to cool slightly.
  6. Quickly scoop the hot, cooked rice into your wide, non-metallic mixing vessel (such as a large glass bowl or wooden Hangiri). Spread the rice evenly. Pour the slightly cooled sushi-zu evenly over the surface of the rice.
  7. Using a wooden or silicone spatula, immediately begin the folding and cooling process. Use a careful 'cutting' motion (slicing down vertically and then turning the rice over), rather than stirring or mashing, to distribute the seasoning without breaking the delicate grains.
  8. While folding, use a handheld fan to rapidly cool the rice. Continue folding and fanning until the rice is just above room temperature (around body temperature). This quick cooling ensures the characteristic glossy finish.
  9. Cover the seasoned rice with a damp, clean tea towel until ready to use. Never refrigerate sushi rice, as it will harden and lose its texture.
