Manual method: it is a crazy challenge to arm strength and endurance.

1.) Use two chopsticks to stir in circles all the time in the same direction. This method is the most exhausting. Without an hour, egg whites are hard to get fat and exercise very much.

2.) Use a manual whisk to stir in circles all the time in the same direction. This method is more convenient than using chopsticks, and generally takes 40 minutes.

Electric mode: electric egg beater, 5- 15 minutes (depending on the power of the eggbeater, my eggbeater is 500w, and I can make three egg whites in 5 minutes).

It is also affected by temperature and egg freshness. For example, eggs taken out of the refrigerator should be preheated first. Eggs are not very fresh. Lemon, white vinegar or Tatar powder can be dripped.

The egg white is beaten in place and mixed with flour evenly, and the taste is naturally soft.

If protein doesn't deliver enough, you can also add baking powder to the flour to remedy it.
