I think what they say is a little commercial! Make custard at home! My practice feels very good! Years of experience, I think! First of all, the water temperature for making custard should be around 60℃. Never use cold water, beat the eggs into a bowl and add salt to break them up! Add warm water and stir well! The ratio is two to three and a half times! Finally, knock off the floating foam with a small spoon! After the water is boiled, put it in the pot drawer and steam for 8 ~ 10 minutes! Ok. Then take a small bowl, put out smoke, vinegar and sesame oil, and pour it on the custard. You can eat! Super smooth and tender! Those who have many years of experience can try!
