Benefits of adding lemon slices to boiling water for eggs

Adding lemon slices to water when boiling eggs can improve the process by making the shells easier to peel. The citric acid in the lemon interacts with the calcium carbonate in the eggshells, weakening them slightly to prevent the shell from sticking to the egg white.

Additionally, lemon can help reduce unpleasant odors and limit surface bacteria due to its acidity. It may also help prevent eggs from cracking during the boiling process by helping the shell better withstand sudden temperature changes. If lemon is unavailable, vinegar can be used as an alternative due to its acetic acid content.
