1. Ingredients: 4 eggs, appropriate amount of sugar.

2. Accessories: a drop of white vinegar and a little salt.

3. Practice.

(1) Beat 4 eggs and separate the egg white and egg yolk.

(2) Beat 4 egg whites until there is a small layer of small bubbles on the egg whites.

(3) Add a little salt, a drop of white vinegar, and a spoonful of sugar (the spoon is an ordinary small iron spoon), and continue to beat the egg whites.

(4) When the mixture is a little thick, add another spoonful of sugar and continue beating.

(5) Beat until it feels thicker than the egg white in step 4, add a spoonful of sugar and continue beating.

(6) After step 5, beat for about 10 minutes. Try to use a whisk to lift the egg whites you beat. If the egg whites can stand up, it means your cream has been beaten.
