Start by rinsing the rice. In a bowl, add the rice and water. Mix the rice and the water with your hands. Discard the water.
Repeat this process around 3-4 times or until the water is more translucid.
Drain the rice well. You can use a strainer and leave the rice there for about 5 minutes.
Add the drained rice in a pot with the water. Let it rest for 20 minutes before cooking. Turn on to medium-high heat and wait until the water is boiling.
Once it is boiling, reduce the heat to low and partially close the pot. (Do NOT stir the rice)
Let the rice cook for about 12 minutes or until the water is completely absorbed/evaporated. After the time, you can carefully use a fork to separate the rice and have a look at the bottom of the pan. If there is still water, let it cook (with the lid partially on) for another couple of minutes).
Turn off the heat, remove from the store and close the lid. Let the rice rest for 10 minutes. (Do not skip this step, it is very important).
Mix all ingredients for the seasoning in a microwave-safe bowl. Microwave for 1 minute, or until all sugar is dissolved.
Spread the rice into a large bowl or baking tray. If you spread the rice more, it cools faster.
Pour the sushi seasoning on top of the rice and gently mix it (you don't want the grains to break).
While gently mixing the rice, vigorously fan the rice. You can use a wood fan, if you don't have one, then maybe a carton for example. This step is important because it helps to remove excess moisture from the rice. The sushi rice is ready
