Before baking sweet potatoes, preheat the oven, and the baked sweet potatoes will taste better. Before baking the sweet potato, it is necessary to clean it, remove the sediment on the surface, and then dry the water with a paper towel, so that it will be more hygienic to eat. Sweet potato can be baked directly in the oven, or it can be wrapped in a layer of tin foil and baked again. The baked sweet potato will be softer and more fragrant.

The specific operation method is to add distilled water to the water tank and push it to the bottom until you hear a "beep", then press the power switch, press the "Pure Steam" button to display the temperature as 100 degree, and press the "+"button to adjust the temperature to the required degree. Confirm the start of cooking (if there is no steam at the steam outlet, immediately check whether the water tank is not properly placed).
