1. The purple sweet potato is peeled and cut into small pieces. After the steamer is steamed, it is steamed in the steamer for 15 minutes (the chopsticks can pierce it), and then mashed into a puree while it is hot.
2. Add sugar, whipped cream, salt, and a little mozzarella cheese, mix well, put it in a container (remember to add tin foil, otherwise it is difficult to wash), and then sprinkle a layer of mozzarella cheese. PS. First taste the sweetness, and then add or not add sugar according to your preference. This step is done while it is hot.
3. Preheat the oven to 180 degrees and bake for 10-15 minutes.
4. If you like a softer taste, you can have a little more whipped cream, and the final purple potato mash should not be too thin.
