: the method of choosing eggs
Look: Look at the color, cleanliness and cracks of eggshells. The fresh egg shell is complete and dull, with a layer of white powder on the surface, which gives people a rough feeling when touching the shell. In addition, carefully observe the egg noodles. We can't buy egg noodles if they are black or have feces and cracks. At the same time, don't buy egg noodles with uneven color or many pockmarks.
Two shakes: When buying an egg, hold the egg with your thumb, forefinger and middle finger and shake it. Those who have no sound are fresh eggs, and those who have sound are bad guys. If there is no sound, it means that the whole egg air chamber and yolk are complete; It may be an old egg with a voice.
Three lights: Hold the egg lightly with your hand and observe the light. Good egg white and yolk are clear and translucent, with a small air chamber at one end. If the egg is stale, it is dark and the empty room is big; Old or spoiled eggs will be dyed.
In addition, if you want to judge whether the eggs you bought home are fresh, you can also use the up-and-down method. Put the eggs in clear water, and the ones with the tips facing down are fresh eggs. If the eggs bought home are not particularly dirty, it is best not to wash them, keep your head down and put them in the refrigerator.
