Okay little one, have you heard of bird's nest soup? It's a popular and special soup in some parts of Asia. The main ingredient of this soup is a nest that is made by a type of bird called a swiftlet. These nests are made from solidified saliva of the swiftlet bird.
Now, some of these nests are completely made up of bird saliva while others may have twigs, feathers and other debris sticking to them. If they have these other things, they are not good for human consumption and are considered low quality bird's nests.
On the other hand, if the nest is pure and made up of only bird saliva, it is a high quality bird's nest and is very valuable. This nest is also known as "edible bird's nest" because unlike low quality ones, it is safe and healthy for humans to eat.
Edible bird's nest is very rich in nutrients and is believed to have many benefits for our health. It is said that it could help with digestion, improve the immune system, and even have anti-aging properties!
In terms of cooking, bird's nest soup is usually made by boiling the nest in water until it becomes a gelatinous mixture. It is then typically served with chicken and other ingredients.
So there you have it, little one! Edible bird's nest is a special ingredient that is valued for its health benefits and is used to make a delicious and nutritious soup.
