Cooking Steps

1. 

   Step1:Cut the sweet potatoes in half. Steam in a steamer for 15 minutes. Steam to 8 and you can easily dig out the sweet potato pulp. Choose sweet potatoes with red flesh. They will be more fragrant when baked.

2. 

   Step2:After steaming, use a small spoon to dig out the sweet potato pulp. Leave more on the edge. If it is too thin, the sweet potato will collapse easily. Be careful not to empty the bottom. It will be used as a container later.

3. 

   Step3:Add 45g of butter, 70ml of milk, 30g of mozzarella cheese and 1 tablespoon of sugar to the sweet potato. Mash and stir well.

4. 

   Step4:Put the mashed sweet potato into a small bowl. Smooth the surface. Sprinkle with mozzarella cheese. Brush some yolk liquid on the surface. It's more golden and nice to bake.

5. 

   Step5:Put the sweet potatoes in the preheated oven. Heat the lower layer up and down. Bake for 1520 minutes at 180 degrees. When the cheese on the surface is melted and colored, you can come out.

   Step6:Fragrant, soft and sweet. Milk is full of fragrance. It's very delicious
