Rinse the rice very well. Short-grained rice is ideal for this dish. The next one is the most important. Put the rice on the fire (do not cover it with a lid!) and bring to a boil. As soon as the water boils (as soon as the first bubbles appear), cover it with a lid and cook for 5 minutes over high heat. Then reduce the heat to low and cook for another 10 minutes. After that, remove the rice from the heat and leave for 15 minutes. After the rice has been removed from the heat and 15 minutes have passed, you can remove the lid and take out the rice.
