The operation steps are as follows:

1. Put the egg white in a container, add a little lemon juice (or white vinegar), beat with electric egg beater until it bubbles, and add one-third sugar.

2, continue to send, when the egg white foam disappears, showing a delicate and smooth state, add one-third of the sugar.

3. When the protein thickens, add the last third of the sugar.

4. When a line appears, hold up the eggbeater and look at it. It is a small upright corner, so the sending is completed.
