1. Wash it first, and spread a layer of greaseproof paper on the baking tray. (The purpose is because sweet potatoes will emit oil when baked, and it is not easy to wash them when they fall on the baking tray. If not, you can leave it, that is, the baking tray should be soaked in water for a while. )

2, oven temperature: the highest temperature of my oven is 230 degrees, and the fire is set up and down for 60 minutes. (This time refers to the sweet potato with a size of 2 or more. If the red one is small, it can be reduced to 50 minutes. )

You can pinch it with gloves then. It would be nice if the middle is soft. If your heart is hard, you have to bake it again 10-20 minutes. If you like oily, you should bake it for a while. This varies from person to person. I prefer oily sweet potato, which will be sweeter.
