There are many ways to separate the egg white and yolk: 1. Break the egg shell and divide it into two halves, and pour half of it back and forth with both hands, so that the egg white flows into the bowl and the yolk remains in the shell until all the egg white flows into the bowl, and only the yolk is in the shell. But if the eggshell is thin, it will not work if it is broken into many pieces. 2. Use an egg separator. Put the eggs into a bowl and use the egg separator to hold the yolk, or put the eggs into a bowl and put them directly into the egg separator, and then pick up the egg separator. However, if it is a very fresh egg, the egg white is particularly thick, and it takes a long time for the egg separator to hold the yolk to leak, and sometimes the yolk will be stuck by the egg separator to leak the yolk. I have encountered this situation, and then I don't need the egg separator. 3. Squeeze the mineral water bottle and suck some egg yolks, one at a time, which I think is the fastest. I always feel that it is not good to suck egg whites with mineral water bottles when shooting videos, so I don't need them. Besides, I always have to keep empty mineral water bottles at home, especially the bottle mouth. It is inconvenient to throw one at a time or wash them after use. 4. I think it's most undesirable to hold it directly by hand. It's too unsightly. Besides, the eggshells should be washed very clean in advance before you can beat the eggs directly. Otherwise, it's unsanitary. How many people can wash the eggs so clean before beating them? 5. Use a spoon about the size of the yolk, put the egg into the bowl and hold the yolk directly with the spoon. Even if the egg is fresh, tilt the spoon slightly and turn it slowly at the edge of the bowl to cut off the egg whites stuck outside the yolk. I like the last of these five methods best. I hope my answer is helpful to you.
