Boil in cold water 10 minute.

After washing the eggs, soak them in a pot filled with water for one minute, boil them with strong fire, and cook them with slow fire for 8 minutes after the water boils, so that not only the eggs are not easy to boil and break, but the yolk inside is golden yellow after peeling, which is beautiful and delicious. Don't cook for too long, otherwise ferrous ions in egg yolk will react with sulfur ions to form brown precipitate of ferrous sulfide, which will lead to the egg yolk turning gray-green with the smell of sulfide, which will also hinder the absorption of iron by human body after eating and reduce the digestibility of eggs.

How long does the egg cook in boiling water?

Generally, it can be cooked after boiling for 6-8 minutes.

If you don't like to eat well-done, you only need to cook it for about 4 minutes, and the egg yolk is half of the sugar. If you cook it for about 5 minutes, the egg yolk is slightly solidified or slightly sugary. You can decide the cooking time according to your taste preferences.

pay attention to

When the egg is boiled for 4 minutes, it happens to be a delicious egg. At this time, the anti-nutritional substances (biotin-binding protein and egg inhibitor) of the egg are destroyed, and the nutrients can be retained to the greatest extent, but salmonella may not be fully killed. It is not recommended for the elderly and children with fragile gastrointestinal function.

What happens when you eat an immature egg?

Some people have a good stomach, so they may not feel uncomfortable after eating the immature eggs. Generally, they should drink more water to promote the metabolism of the immature eggs. However, if the digestive function of the stomach is poor or the resistance is not strong, eating the immature eggs may cause symptoms of diarrhea and abdominal pain, because the immature eggs may contain pathogenic salmonella, mold or parasitic eggs. If the eggs are not fresh, the carrier rate will be higher, and these bacteria will be eaten by the human body without being killed by high temperature, which will easily lead to gastrointestinal discomfort.

4 Tips for Boiling Eggs

1, add a little salt

Adding a little salt to the boiled water can not only make the eggs taste better, but also make some raw eggs with small cracks not crack during cooking.

2, as soon as possible after cooking.

Eggs should be picked up as soon as possible after being cooked, and should not be cooked in the pot for a long time. Otherwise, the persistent high temperature will not only make the eggs overcooked, but also reduce the taste, and make the eggshells more fragile and crack. The fished eggs can be shelled better after being cooled in cold water.

3. Frozen eggs should be placed at room temperature before cooking.

The eggs refrigerated in the refrigerator need to be taken out and heated at room temperature first, and cannot be boiled directly in water, otherwise the stimulation of sudden cooling and heating is easy to cook until the eggshell bursts.

4. Soak the eggs in cold water before boiling

Before boiling eggs, you can wash them, soak them in cold water for about half an hour, then put them in the pot and add some water to cook them, so that a little water enters the egg first, which can make a gap between the eggshell and the protein due to high temperature, so that it is easy to shell, and the shelled eggs are relatively complete.
