Pour milk, orange juice and fine sugar into a bowl, heat the water and stir until the white sugar just melts. Pour the eggs into the milk and mix well.
Sift the egg mixture twice and pour it into the container. In order to ensure a delicate taste, after sieving, let it sit for about half an hour.
Put the water in the pot, put the container of the egg liquid into the pot, turn the water to a small fire for 10 minutes, turn off the heat and wait for two or three minutes to open the lid.
