1. Adding salt when boiling eggs can change the density of water, so that the position of eggs in water is not at the bottom of the container, which can effectively avoid boiling.

2, boiled eggs with salt can slightly change the taste of eggs, so boiled eggs can reduce the fishy smell.

: Precautions for boiled eggs:

1, don't boil eggs with boiling water.

First of all, boiling water will make the eggs roll around in the pot, which will easily break the eggshell and even expose protein. Secondly, protein in eggs does not need high temperature, which is generally 60℃-87℃, while the temperature of boiled water can reach 100℃. If boiled in boiling water, protein may be as old as an eraser. Therefore, when cooking eggs, open the lid and let the water bubble slightly instead of boiling.

2, the cooking time should be short, and it should be cooled after cooking.

It takes 10 minutes to cook an egg with fully cooked protein and completely solidified yolk, but it takes about 6 minutes if you want a boiled egg with tender yolk. If the eggs are boiled too long, they will smell of sulfur. In addition, it should be noted that the eggs should be cooled with cold water immediately after they are out of the pot, otherwise the residual temperature will make the eggs continue to be heated and get old.
