working methods
1. Choose bird's nest and let it soak in pure water for about 4 hours.
2. Soak the bird's nest, tear it into strips, and clean it with a fine mesh colander.
3. Put the soaked bird's nest in a saucepan and stew it in water. Soak in the bird's nest and stew for 30 minutes. No rock sugar for the time being.
4. Put a bag of milk into the pot and boil it. At this time, add the right amount of rock sugar.
Mix the boiled milk with the bird's nest and a bowl of midnight snack will be ready.
