Ingredients: sweet potato, tin foil
Production steps
1. Clean the sweet potato and use kitchen paper to absorb water. There should be no broken skin or holes on the surface of sweet potato. It is recommended to choose a slender one, not a big one.
2. Preheat the oven for 10 minute, adjust the temperature to 230 degrees, spread a layer of tin foil on the baking tray, and put the sweet potatoes into the baking tray. (Note: Be sure to put tin foil. Putting tin foil at the bottom can prevent mucus from sticking to the baking tray, which is beneficial to the cleaning of the baking tray. )
3. Put the baking tray in the oven, and adjust the oven to 2 10 degree and bake for 50 minutes. (Note: The temperature of each oven is slightly different. Pay attention to the observation in the middle to prevent the sweet potato from burning. Just stick it in with chopsticks and it will be cooked. )
