Tips:The red heart sweet potato tastes better, it is sweeter and the starch content is lower than that of the white heart sweet potato, and there are more trace elements.
When roasting, sweet potatoes do not need to be wrapped in tin foil. Cover the baking tray with tin foil, and then put the sweet potatoes on the baking tray. My oven is relatively small, so if you bake it longer, the sweet potatoes will be almost soft when the syrup comes out.
