Chinese Yam, White Fungus, and Sweet Potato Dessert Soup

Prepare the materials.

Soak the white fungus in water in advance until it softens.

Peel the sweet potatoes and cut them into pieces, then soak them in clean water for a while.

Peel the Chinese yam, wash it clean, and cut it into pieces. If not using immediately, soak it in clean water first.

Remove the stems from the soaked white fungus, rinse it clean, and tear it into small pieces.

Put the white fungus into the pot, add an appropriate amount of water, and first boil for 30 minutes.

Add the sweet potatoes and yams, then cook for another half hour.

Finally, add the rock sugar and cook until it melts.
