1. The stewing time of bird's nest varies from 30 minutes to 1 hour. In order to prevent the loss of nutrients in the process of stewing, the stewed bird's nest is bright, smooth and fragrant. It is best to stew bird's nest with ceramic utensils, and purple sand is not recommended, because purple sand is easy to volatilize the ingredients of other medicines stewed before.

2. Put the brewed bird's nest in a stew pot or stainless steel container, add a proper amount of water to cover the bird's nest, and put the stew pot or stainless steel container in a pot with a proper amount of water.

3. Cover the saucepan or stainless steel container cover and pot cover, first boil water with high fire, and then simmer for 30 minutes to 1 hour with low fire.
