Porridge in a rice cooker usually takes about 20 minutes.
If you put some red dates, wolfberry and other qi and blood nourishing foods in it, you can cook it for a longer time, 20 to 30 minutes.
If it is special porridge, such as preserved egg and lean meat porridge, it will take longer, and it will take more than 40 minutes to prepare the ingredients in advance.
Note: The water should not be too much or too little. It can be filled in later. Do not leave people while cooking the porridge. Stir constantly to avoid sticking to the bottom of the pot. If there is a paste smell, it will not taste good.
