You may pre-cook the bird's nest and store in the refrigerator for up to 7 days to be added to dessert, porridge, soup, as additional stuff for pork dumpling etc.
Soak the bird's nest in a bowl of water for 45 mins to one hour.
Use a sifter to filter the water and set the bird's nest aside.
Bring to boil a pot of water and place the bird's nest in a stew pot, making sure the stew water must cover the nest.
Place the stew pot in the pot of boiling water and using low heat for 45 mins.
For simple bird's nest soup, add rock sugar at the end of stewing.
Alternatively, you may add 5-6 pieces of American Ginseng or 4-5 pieces of red dates and simmer with the bird's nest.
Important: Always add rock sugar at the end of stewing not begining as it will spoil the taste of the bird's nest soup.
