Why is adding lemon when boiling eggs effective?
Boiled eggs are a familiar, nutritious and easy-to-prepare dish. However, many people have difficulty peeling or encounter cracked eggs during boiling. A simple tip is to add a few slices of fresh lemon to the boiling water that many people are applying.
According to Dr. Harold McGee - a food expert, lecturer at Stanford University (USA): "The pH of boiled water can affect the structure of the egg white and how eggs separate from the shell.
Lemon contains citric acid, which changes the cooking environment when added to water. This helps egg whites solidify faster when exposed to heat, especially useful if eggs are cracked, limiting egg whites from overflowing.
In addition, the eggshell also becomes easier to handle, helping to peel quickly and neatly, without sticking. This is why many people find that boiled eggs with lemon often have smooth, beautiful surfaces.
Not only that, lemon also helps reduce unpleasant odors during boiling, while creating a light aroma, making the dish more attractive, especially when served in cold dishes such as salads or sandwiches.
Benefits of boiling eggs with lemon
Adding lemon to the boiled egg pot brings many practical benefits in the cooking process:
Easier peel: Reduce the adhesion between the white and the membrane.
Limit cracks in the skin: White blood coagulates quickly, helping to "cover" small cracks.
Reduce fishy smell: Lemon helps neutralize the smell produced when heated.
Increase aesthetics: Eggshells can be brighter and cleaner after boiling.
Improve texture: The whites are firmer, less loose.
According to Professor Kantha Shelke - a food expert at Johns Hopkins University (USA): "Small changes in cooking can make a clear difference in the quality of the dish.
To apply, just add a few slices of lemon or a little lemon juice to the pot when boiling eggs as usual. You can add a little salt to increase the effectiveness, then boil for about 5-7 minutes depending on the desired ripeness.
It can be seen that a small change in cooking not only saves time but also improves the quality of the dish. This is a simple but useful tip, suitable for every family.
