Generally speaking, fresh eggs are easier to be sent, but the stability after being sent is worse. It is more difficult to send frozen eggs, but the stability is better.
In addition, when sending egg whites, we should pay attention to two details: the tools used should be water-free and oil-free, and the egg whites and yolks should be separated cleanly.
Generally speaking, you accidentally get water when you send egg whites, and there is no way to save them if there is more water, because you can't send them at all. If there is less water, you can add tartar powder and try again.
if the egg white is mixed with oil and there is a small amount of oil, although it can be sent away, it will greatly affect the sending effect of the egg white. if there is more oil mixed in the egg white, it is recommended to make it again, because this kind of egg white can't be sent away at all.
If the egg white is sent away, you can add some baking powder to the egg white, or put it in the refrigerator for a few minutes before sending it away. These two methods are both good.
When adding fine sugar to the egg white, the structure of the egg white will be more stable.
