Boiled egg water boils and cooks for 5-7 minutes.

The cooking time of an egg is one of the key factors affecting the taste and nutritional value of an egg. Generally speaking, 5-7 minutes after boiling the water for cooking an egg is the most suitable time. If the cooking time is too short, the eggs may not be fully cooked, the yolk is raw, after eating is not conducive to human health. And if boiled for too long, it will cause the eggs to become old and taste bad.

In order to ensure that the boiled eggs are tender and have a high nutritional value, it is recommended that the water be boiled first when boiling the eggs, and then the washed eggs be put into the pot and slowly boiled over a low heat. This will enable the eggs to be gradually heated and evenly cooked, and at the same time avoid overcooking the eggs because the water has been boiled for too long.
