You should prepare a flashlight and a small paper box first, and then open a small round hole at the bottom of the paper box, which is slightly smaller than an egg.

Next, you can shake the eggs in various ways. If you feel the shaking is almost enough, put the eggs in the carton, put the flashlight under the carton and aim at the round hole. At this time, you can observe the inside of the egg by turning on the flashlight.

If the inside of the egg is uniform everywhere, it means there is no need to shake the egg. If there is still a big shadow, keep shaking. In order to observe more clearly, you can observe the egg once and then shake it. The circular shadow in the middle is the yolk.

After the eggs are shaken well, put cold water in the pot, boil the water with medium heat, and then cook it with low heat for about 7 minutes, and you can cook the perfect golden eggs. Many friends will explode eggs when cooking, mainly because they keep the fire burning. Remember to boil over medium heat and then cook over low heat.
