Ingredients: 5g of bird's nest. Accessories: 5g of rock sugar. The specific method is as follows: 1. Add bird's nest to the bird's nest cup and soak it in pure water (soft water) for 8-10 hours. The best taste is to soak it, and it can also be doubled in size.

2. Remove the bird's feathers, pour out the soaking water gently, repeat 3 times and be sure to use soft water.

3. Tear the bird's nest into strips smoothly, which will help preserve the taste.

4. Add soft water into a pot and cook for about 30 minutes.

5. Add rock sugar and serve.
