How long should a hard-boiled egg cook?
Correct Answer
C. 10-15 minutes
Explanation
A hard-boiled egg should cook for 10-15 minutes. This allows the egg yolk to fully set and become firm while the egg white also cooks through. Cooking the egg for too long can result in a dry and rubbery texture, while cooking it for too short a time may leave it undercooked and runny. Therefore, the optimal cooking time for a hard-boiled egg is 10-15 minutes.
2.
It is best to cook an egg with the lid on.
Correct Answer
A. True
Explanation
Cooking an egg with the lid on helps to retain heat and moisture, resulting in a more evenly cooked and tender egg. The lid creates a sealed environment, trapping the steam generated by the egg, which helps to cook the egg from both the top and bottom simultaneously. This method also reduces the cooking time and prevents the egg from drying out. Therefore, it is recommended to cook an egg with the lid on for the best results.
3.
What should you add to the water to prevent the egg from cracking?
Correct Answer
C. Vinegar
Explanation
Adding vinegar to the water helps prevent the egg from cracking because vinegar is acidic. The acidity of vinegar helps to strengthen the eggshell by reacting with the calcium carbonate present in the shell, making it more resistant to cracking. This is particularly useful when boiling eggs as the heat can cause the shell to become more fragile.
4.
Should you add the eggs to the water before it begins to boil or after?
Correct Answer
A. Before
Explanation
Adding the eggs to the water before it begins to boil is the correct answer because it allows the eggs to gradually heat up along with the water, preventing them from cracking due to a sudden change in temperature. When the water starts boiling, the eggs will already be at the same temperature as the water, ensuring even cooking and reducing the risk of overcooking or undercooking the eggs.
5.
If you use eggs at room temperature, the cooking time will be less.
Correct Answer
A. True
Explanation
When eggs are at room temperature, they will cook faster compared to cold eggs. This is because the heat from the cooking process can penetrate the eggs more easily when they are at room temperature, leading to a quicker cooking time. Cold eggs, on the other hand, take longer to cook as they need more time for the heat to reach the center and cook them thoroughly. Therefore, using eggs at room temperature can indeed result in a shorter cooking time.
6.
Eggs should be in the water for some time, even after the water has boiled.
Correct Answer
A. True
Explanation
Eggs should be left in the water for some time after it has boiled to ensure that they are fully cooked. This extra time allows the heat to penetrate the egg and cook it thoroughly, avoiding any raw or undercooked parts. If the eggs are removed immediately after boiling, there is a higher chance that they may not be cooked all the way through. Therefore, it is important to leave the eggs in the hot water for a few minutes after boiling to achieve the desired level of doneness.
7.
Peeling a boiled egg is very easy, even for first-timers.
Correct Answer
B. False
Explanation
The statement claims that peeling a boiled egg is very easy, even for first-timers. However, this is not necessarily true as peeling a boiled egg can be a challenging task for some people, especially if the egg is not cooked properly or if the shell is difficult to remove. Therefore, the correct answer is False.
8.
Eggs should always be boiled on a low flame.
Correct Answer
B. False
Explanation
There is no specific requirement to always boil eggs on a low flame. The cooking time and heat level for boiling eggs can vary depending on personal preference and the desired doneness of the eggs. Some people prefer to boil eggs on high heat for a shorter cooking time, while others prefer a slower cooking process on low heat. Therefore, the statement is false as it implies a universal rule that does not exist.
9.
Water should be enough to cover the eggs.
Correct Answer
A. True
Explanation
The statement is true because when boiling eggs, it is important to have enough water to completely cover them. This ensures that the eggs cook evenly and prevents them from cracking due to direct contact with the heat source. If the eggs are not fully submerged, they may not cook properly, resulting in unevenly cooked eggs. Therefore, it is necessary to have enough water to cover the eggs completely while boiling them.
10.
How can you prevent the york and the white from escaping from the cracks of an eggshell?
Correct Answer
C. With the help of salt
Explanation
Salt can be used to prevent the yolk and the white from escaping from the cracks of an eggshell because salt has the ability to coagulate proteins. When salt is applied to the cracked eggshell, it draws out the moisture and forms a gel-like substance with the proteins in the egg, sealing the cracks and preventing any further leakage. This method is commonly used in cooking to salvage cracked eggs and ensure that the contents stay intact during cooking.
