How do you know if the eggs are cooked?
In daily life, boiling eggs seems simple, but how to judge whether the eggs are cooked is a science. This article will combine the hot topics and hot content on the Internet in the past 10 days to introduce you in detail how to judge whether an egg is cooked, and provide structured data for reference.
1. How to judge whether eggs are cooked
1.time judgment method: Based on the length of time you cook the eggs, you can initially judge the doneness of the eggs. The following is a guide to the time required for different doneness levels:
| doneness | Cooking time (minutes) |
|---|---|
| Soft-boiled eggs | 4-6 |
| soft boiled eggs | 6-8 |
| Hard boiled eggs | 10-12 |
2.rotation method: Place the hard-boiled eggs on a flat table and gently rotate them with your fingers. If the egg spins smoothly and quickly, the yolk is solidified (fully cooked); if the egg spins erratically or slowly, it may be half-cooked or runny.
3.Illumination method: Shine a flashlight on the egg in a dark environment. If light can pass through the shell, the egg is undercooked; if light cannot pass through, the egg is fully cooked.
4.shaking method: Gently shake the eggs. If you hear the sound of liquid flowing, the eggs are not fully cooked; if there is no sound, the eggs are fully cooked.
2. Precautions for different cooking methods
1.Cold water cooking method: Put the eggs into cold water and start timing after the water boils. This method is suitable for cooking hard-boiled eggs, but you need to pay attention to the heat control.
2.Hot water boiling method: Add eggs after the water is boiled for more accurate timing, suitable for boiling soft-boiled eggs or half-boiled eggs.
3.Steaming method: Use a steamer to steam eggs. The time is slightly longer than boiling, but the eggs are less likely to break.
3. Frequently Asked Questions
| question | Answer |
|---|---|
| Why do eggs crack when cooked? | It may be that the water temperature is too high or the eggs were taken directly from the refrigerator and put into hot water. |
| What should I do if the eggshell is difficult to peel after boiling it? | Immediately after cooking, soak in cold water and use the principle of thermal expansion and contraction to separate the eggshell and protein. |
| How to preserve hard-boiled eggs? | Store in the refrigerator and consume within 3 days. |
4. Tips for boiling eggs
1. Adding a small amount of salt or vinegar when boiling eggs can prevent the eggshells from cracking.
2. Use room temperature eggs instead of refrigerated eggs to reduce cooking time.
3. Rinse with cold water immediately after cooking, which can prevent the residual heat from continuing to cook and facilitate shelling.
5. Nutrition Tips

Eggs are a high-quality source of protein, and eggs with different degrees of ripeness have slightly different nutrient absorption rates. The protein absorption rate of hard-boiled eggs is the highest, reaching more than 90%, while the vitamins of soft-boiled eggs are more complete.
Through the above methods and techniques, I believe you have mastered the key to judging whether the eggs are cooked. Whether for breakfast, lunch, or as a salad topping, a perfectly cooked egg adds nutrition and flavor to any meal.
