First, measure the rice in the rice cup, pour it into the pressure cooker, and rinse it with clear water for at least 3 times, not too many times, so as not to destroy the nutrition. Then, add a proper amount of water and cook the rice. Generally speaking, water is only a little less than rice. Cover the lid with high pressure. It is best to soak rice for more than half an hour to cook dry rice, so that the cooked rice is soft. After soaking for half an hour, turn on the gas and fire. When the pressure cooker blows for the first time, it is the sound of the pressure valve opening. 10 minutes or so, blow air into the pressure cooker, turn off the fire, and then turn off the fire at high pressure for 2 minutes. Turn off the fire after two minutes of high pressure, and then open the pressure cooker for rice after the pressure valve on the pressure cooker drops. In this way, it only takes 20 minutes to cook delicious rice.
