generally, eggs can be boiled for 5-1 minutes. Wash the eggs before boiling them, or they will get dirty. Boil in water until the water boils, and cook for 5 minutes. Most of the egg whites are cooked, but the yolk is not yet mature. Boil for 7 minutes, the egg white is ripe, and the yolk is ripe. This time is what we often call sugar-soaked eggs; The egg white and yolk are ripe after cooking for 1 minutes. At this time, the taste is just right. If the cooking time is too long, it will destroy the nutrients of the eggs and the taste will become old.
