- Please note: 1 rice cooker cup is 180 ml. So when you use Japanese rice cooker, 1 cup means Japanese rice cooker cup.
- Put rice in a large bowl. Rinse the rice and discard the water immediately. Rice absorbs water very quickly when you start washing, so don't let the rice absorb the unclear water. Repeat this process 1-2 times.
- Now use your fingers to gently wash the rice by moving in a circular motion.
- Rinse and discard water. Repeat this process 3-4 times.
- Let the rice soak in water for 30 minutes.
- Transfer the rice into a sieve and drain completely.
- Gently clean the dashi kombu with a damp cloth but leave the white powdery substances which contribute to the umami flavor in dashi. Do not wash the kombu.
- Put the rice in the rice cooker bowl and add water (not hot or warm) to just under the 3 cup line. If your rice cooker has "Sushi" option, add water to 3 cup line for "Sushi". Since you add sushi vinegar to the rice, rice is on the firm side. If you cook rice without a rice cooker, water should be about 540 ml. Place the kombu on top of the rice and start cooking.
- To make sushi vinegar, combine rice vinegar, sugar, and salt in a small saucepan and bring it to a boil over medium high heat. Whisk until the sugar is completely dissolved. You can also put the ingredients in a microwave-safe bowl and microwave for 1 minute, or till sugar is dissolved. Set aside to let it cool.
- When the rice is cooked, moisten sushi oke/hangiri (a round, flat-bottom wooden tub) or a large bowl with water so the rice will not stick. Transfer the cooked rice into the sushi oke and spread out evenly so the rice will cool faster. While it’s hot, pour sushi vinegar over the rice.
- With a rice paddle, slice the rice at a 45 degree to separate the rice grains instead of mixing.
- Then gently flip the rice in between slices. Repeat this process till rice is cooled.
- Keep the rice covered with a damp towel (or paper towel) until ready to use.
1 rice cooker cup is 180 ml, not same as 1 US cup. 1 cup will make 2 cups of cooked rice. Please use Japanese short grain rice for making sushi. There is a convenient Sushi Seasoning available at Japanese/Asian grocery store. You make regular steamed rice, and add the seasonings after rice is cooked. Instead of kombu, you can add ½ tsp. (Kombucha) If you don't have a rice cooker, please follow How To Make Steamed Rice (in a pot). You can buy sushi oke/hangiri here. Recipe by Namiko Chen of Just One Cookbook.
