Stew the bird's nest before putting it in. For specific instructions, please refer to the following steps: Ingredients: 3-5 grams of dry bird's nest, 60-80 ml of milk, and 4-5 grams of rock sugar. Method 1. First prepare a clean bowl, preferably white porcelain or glass. Be careful not to have oil stains or other stains. 2. Soak the bird's nest in purified water or cool boiled water for two hours. The water needs to be changed several times during the process. 3. After picking and cleaning the bird's nest, tear the bird's nest into thin strips. 4. Put the bird's nest into a stew pot, simmer over low heat and water for about 30 minutes. 5. Pour the fresh milk into another small pot, add rock sugar, and stir while heating to prevent the milk from sticking to the pot and becoming scorched. Bring to a boil and turn off the heat. 6. Pour the hot milk into the bird's nest, stir it gently and the delicious and nutritious bird's nest stewed in milk is ready to eat.
