Production skill
(1) Avoid adding raw water and hot water.
Add raw water because there is air in tap water. When water is boiled, air will be discharged, and small beehives will appear in custard, which will affect the quality of custard, lack tenderness and destroy its nutrients. It is not advisable to use hot boiled water, otherwise the boiled water will heat the egg liquid before steaming, which will destroy the nutrition and even steam the egg custard.
(2) Avoid stirring the egg liquid violently.
Stir the egg liquid vigorously or for a long time before steaming will make the egg liquid foam, and the egg liquid will not dissolve into one when steaming after stirring.
