For shredded sweet potatoes, you don’t need to wait for the sweet potatoes to cool down. Just pour the syrup directly on top. The sugar will solidify if left for a long time.
If you want to pull out the silk from this dish, you need to add maltose. When cooking the syrup, you need to control the fire, otherwise the syrup will burn.
When eating it hot, first soak the sweet potato pieces in cold boiling water. The sugar coating on the sweet potato pieces will harden and become crispy when exposed to water, making it sweet and crispy in the mouth.
