The ratio of rice to water is 1: 3, and excessive water is not allowed, which can only be added to four fifths of the whole pressure cooker. If there is too much water, it will overflow when cooking porridge.

The principle of pressure cooker cooking porridge is to seal the pot, so that the pressure in the pot is greater than atmospheric pressure, so that porridge is cooked faster, usually in about 20 minutes. The most important thing for pressure cooker to cook porridge is to keep the pressure limiting valve hole unobstructed. After cooking, be sure to let off the gas before opening the lid.

Matters needing attention in cooking porridge in pressure cooker

1. The vent of the pressure cooker is very important. If the vent hole is blocked, the steam in the pot can't be discharged, so all of it will gather in the pot and explode when it reaches a certain pressure. Therefore, before use, be sure to check whether the exhaust hole is unblocked and whether there are rice grains or food residues blocked in it. If there is, it should be removed quickly. In addition, check whether the safety valve on the pressure cooker is tightened and whether there is air leakage. Only the seal is tightened.

2. After cooking, it can be naturally cooled at room temperature. If you want to eat right away, you can use forced cooling (shower or soaking in water) to reduce stress. After cooling, you can gently lift the pressure limiting valve to release the remaining gas.
