If you cook eggs in a pot with cold water, wait for the water to boil slowly. In this process, the temperature is relatively low, and the egg protein solidifies relatively slowly. Generally, the water is boiled for 5 minutes, and then boiled for 3 minutes, so that the inside of the egg is completely cooked. This kind of yolk will be slightly dry, but it can ensure that the eggs are gradually heated and cooked evenly. Eggs should be picked up as soon as possible after they are cooked, and should not be cooked in the pot for a long time.
