Take rice for sushi. Similar to this. Rice needs to be prepared. Pour the rice into a large bowl. Fill the rice with a large amount of purified (boiled, potable) water and mix quickly with a wooden spatula. Pour some more water. If the water is still cloudy this time, repeat the rice washing procedure until the water becomes clear. Discard the washed rice in a colander, drain all the water completely, and then soak it in cold water for 20-60 minutes. After that, put the rice back in a colander and let it dry (20 minutes). This is necessary so that the grains absorb moisture and swell. Don't forget to cook the rice in advance. Half an hour should pass between drying and cooking, then the result will be as close to ideal as possible.
