1, on the left are common eggs in the market (different sizes, this egg is of medium height), and on the right are fools (fools vary greatly in size, so this egg belongs to the best among fools). You can still see that the left egg is fatter than the right egg.

2. After opening, take a closer look at the size of the yolk. The right side seems a little bigger, the color difference is obvious, and the right side is more yellow.

3. Look at this. It is more obvious that the overall weight of the left side is much larger than that of the right side. Probably weighed it. After hulling, the left side weighs 49g and the right side weighs 43g.

4, the grass egg white is clear and sticky, slightly yellow, the egg yolk is golden in color, floating on the egg green, not sinking, a toothpick inserted in the middle of the egg yolk can stand upright, its eggshell is tough and thick, with high calcium content, not as fragile as other eggshells. Peel a hard-boiled egg and rub it in your hand. Even if the egg is squashed, protein will not crack, and it is still a complete egg.

5. Look at the brightness and cleanliness of eggshells. If the eggshell surface is bright, it means that the storage time is long and the eggshell surface of fresh eggs has a strong three-dimensional effect; Pick up the egg and shake it in your ear. If there is noise, it means it is not fresh. Put the egg in a dark place and shine a small flashlight on the larger end of the egg. The smaller the air chamber (that is, the gap inside the egg), the fresher it is.
