1. Wash the sago and soak it in a little water for half an hour. You don't need much water, just a little. Soak sago until it can be softened by hand. You can pour out the excess water.

2. The time for soaking sago can be used to steam purple potatoes. Wash the purple potato, steam it, peel it, and roll it into purple potato paste.

3. Add appropriate amount of sugar to sago, add a little starch and mix well. Starch is added to make sago easy to make dough.

4. Half a slice of cheese is stacked into small doses, and purple potato puree and sago puree are also made into small doses with uniform size.

5. You can make three kinds of fillings: purple potato cheese heart and purple potato cheese heart. Clamp the stuffing with sago. Simi is harder and better wrapped.

6. Press out the shape with a die.

7. Cover the plate with moon cakes with another plate to block the water vapor. Steam in the pot for half an hour after the water is boiled.
