Soak the eggs in warm water for 5 to 10 minutes. Dry the eggs and separate the egg whites from the egg yolks. The utensils (eg egg splitters, egg whites and egg yolks, whisks, etc.) must not contain oil and water.
Divide 4 egg whites and beat them in one direction (this is a small bubble above the egg white). Put 5g salt, 5g white vinegar, and 15g sugar (a spoon is just a spoonful of an ordinary small spoon).
Continue to quickly beat eggs in the same direction, then add 15g sugar and continue to stir quickly.
When the same direction is a bit thick, add another spoonful of 15g sugar and continue playing.
In the same direction, I played for about 10 minutes and tried to use the egg beater to stir up the egg white. If the egg white can stand up, it means that the egg white has been laid.
