Peel and wash the sweet potato first, cut it into small pieces, and add a proper amount of water to the pot. If you cook sweet potato rice, just put the millet in cold water for 15 minutes, and the sweet sweet potato rice will be ready. For example, the production method of sweet potato corn porridge is basically the same as that of sweet potato rice. The difference is that after the water is boiled, the corn is sprinkled into the pot and boiled for 15 minutes, and then the sweet potato corn porridge is made.
