Procedures for soaking bird’s nest:
Soak bird’s nest in warm water for 30 minutes. After removing feather from the bird’s nest, soak in the water for another 3 hours. Leave the soaking water for later use because it contains nutrition from the bird’s nest.
Pour suitable amount of water and bird’s nest into a stewing pot. Stew over low heat for several hours.
(The stewing time differs according to the origin place)
