There are 3 common egg-boiling methods that you should avoid to prevent bacterial contamination and potential food poisoning.
1. Boiling Eggs in Already Boiling Water
It is a common practice to boil eggs in already boiling water. However, this is a significant mistake as it greatly reduces the quality of the eggs.
When eggs are placed in boiling water, the sudden change in temperature can cause the shells to crack. These cracks provide an entry point for bacteria, such as salmonella, to enter the egg and pose a health risk to the consumer.
That’s why experts recommend starting with cold water when boiling eggs. Besides preventing shell cracking, using cold water ensures that the eggs cook evenly, resulting in a softer and more flavorful outcome.
2. Over-Boiling Eggs
Some people believe that boiling eggs for a longer time makes them safer to eat. However, experts disagree and consider this practice a mistake due to the following reasons:
– Over-boiling can lead to the formation of iron sulfide, which produces an unpleasant odor and discolors the yolk.
– Prolonged boiling also reduces the nutritional value of the eggs. Research has shown that boiling eggs for an extended period leads to a decrease in vitamin content, especially vitamins E and B.
– Eggs contain high levels of linoleic acid, arachidonic acid, and DHA. When exposed to temperatures above 100 degrees Celsius, the oxidation process accelerates, increasing the risk of inflammation.
So, how long should you boil eggs? Here’s an ideal timeline:
– Boil the eggs over high heat for 5 minutes.
– Reduce the heat to low and continue boiling for an additional 3 minutes.
With this boiling time, the egg whites will be soft, and the yolks will be set but not overcooked.
3. Soft-Boiled Eggs
Soft-boiled eggs, with their runny yolks and creamy texture, are a favorite for many. However, this boiling method is not recommended as it can have adverse health effects.
Research has shown that eggs are highly susceptible to bacterial contamination. At temperatures below 71 degrees Celsius, most bacteria are destroyed. However, soft-boiled eggs, with their undercooked yolks, can still harbor bacteria, leading to digestive issues and other health problems.
Tips for Boiling Eggs Without Cracking the Shells
In addition to boiling eggs safely, many people are interested in methods to prevent shell cracking. Here are a few tips from Bếp Eva:
Soak Eggs in Cold Water
Before boiling, soak the eggs in cold water for a while. This helps prevent shell cracking and makes the eggs easier to peel.
Adjust the Heat
Boil the eggs over medium heat to allow them to cook gradually and prevent shell cracking due to rapid expansion.
Prick the Egg Shells
Use a sewing needle to prick a small hole in the wider end of the egg. This end contains air, and by creating a small hole, you allow the air to escape slowly, reducing the pressure and preventing the shell from cracking.
Add Salt and Vinegar
When boiling eggs, add a small amount of vinegar and salt to the water. Be careful not to add too much, as it can have adverse effects. The right amount of salt and vinegar will help prevent shell cracking and make the eggs easier to peel without sticking to the shell.
