Soak dried bird's nest in normal temperature water for 4-6 hours. In order to avoid bacterial growth in summer, the soaking time should not exceed 8 hours. Tear the swollen bird's nest into strips after soaking.

If the edges and corners are still hard, you can cut them off and continue to soak. When they are soft and swollen, they can move on to the next step. Then tear the expanded bird's nest into strips, and put the water and bird's nest in a pot for 30-60 minutes.
