First of all, the reason why the rice cooker is airtight when cooking may be that the steam hole of the rice cooker is blocked. Blocking the steam hole can reduce evaporation, resulting in insufficient pressure, unable to form hot gas and dew gas, which affects the cooking effect. In view of this situation, we can gently clean the steam hole with toothpicks and other tools to make the steam unobstructed.
Secondly, the reason why the rice cooker does not exhaust gas when cooking may also be that there is not enough water added. Because the less water there is, the less steam will be generated, the smaller the external pressure will be, and there will be no venting. At this time, we can add water according to the capacity of the rice cooker, neither too much nor too little, so as not to affect the cooking effect.
Thirdly, the rice cooker does not emit steam when cooking, which may also be caused by too long cooking time. Because the boiling point of the rice cooker is low, don't cook for too long, otherwise it may affect the pressure. When cooking with a rice cooker, you can choose the right time and firepower according to different dishes to achieve good cooking effect.
In a word, rice cookers need to pay attention to details when they are used to cook well. When there is no gas, you can check it from the aspects of cleaning the steam hole, adding water and cooking time. Only in this way can we make delicious and nutritious dishes.
