1. Preparation materials: 250 ml of milk, two eggs, appropriate amount of sugar.

2. First, pour the milk into a small milk pot, heat it over low heat until the milk is slightly boiling. Be careful not to use high heat, and don't walk away, because it will overflow.

3. Pour the boiled milk into a bowl and let it cool naturally.

4. While the milk is cooling, you can separate the egg whites and yolks.

5. Add an appropriate amount of white sugar to the egg whites (you can also add some lemon juice or white vinegar to remove the egg smell), and stir evenly with chopsticks.

6. Pour the egg liquid into the milk.

7. Prepare another empty bowl, put a strainer on it, and filter the mixed liquid. You can also directly use a spoon to skim off the foam on the surface to make the surface smoother.

8. Cover with plastic wrap and poke a few small holes with toothpicks.

9. Put it in a steamer, steam over high heat for about 10 minutes, and simmer for another 5 minutes before it is ready.
