The correct method I know is as follows:

1. Crush donkey-hide gelatin and soak it in rice wine for 48 hours. Fry red dates, walnut kernels and black sesame seeds until cooked and set aside.

2. Put donkey-hide gelatin in the pot, cook over medium heat until bubbling, pour in yellow rock sugar and simmer until thickened, then lower the heat to low.

3. Add red dates, walnuts, wolfberry and black sesame seeds in 3 batches until stringy.

4. Pour donkey hide gelatin into the mold with oiled paper, flatten the oiled paper, let it cool and then refrigerate it in the refrigerator.

5. Take it out after 2 hours.
