Boil the boiled water for 5 minutes, and the undercooked water for at least 20 minutes.
The steps of cooking sweet potatoes and corn in rice cookers are the same. That is: put corn (or sweet potato) in a pot, add water (cold water or hot water), cook for about 20 minutes, then unplug the power supply and let it stew for 10 minutes. Then plug in the electricity, burn for about 20 minutes, unplug the electricity and stew for 10 minutes. Repeat this process until it is cooked.
note:
1, the water quantity should be controlled well, and corn or sweet potato must be submerged. There is little water in the middle, so you have to turn it up and down, and add some water appropriately to facilitate cooking.
2. In the process of cooking, it is necessary to prevent water from overflowing the pot after boiling. You can cook in a pot, cover the pot and stew after boiling.
If you like sweets, you can add a little sugar after cooking.
