Fact 5: How hard they are to peel may be an indicator of freshness
The method of cooking eggs can influence their nutritional value. Cooking at high temperatures, such as frying, can result in increased oxidized cholesterol, whereas boiling eggs at lower temperatures may have a milder effect on cholesterol levels. Consequently, hard-boiled eggs might be more advantageous for heart health compared to other cooking techniques.
Fact 6: There are numerous tricks for peeling hard-boiled eggs.
Fresh eggs are often harder to peel because the egg whites of fresher eggs tend to adhere to the inner shell’s membrane. As eggs age, their acidity diminishes, making it easier to separate the egg white from the shell. To make peeling simpler, store your eggs in the refrigerator for a week or two before boiling them.

Fact 7: Their shelf life might not be as long as you expect.

Fact 8: The custom of consuming hard-boiled eggs has existed for centuries.
Hard-boiled eggs have been savored for thousands of years, with origins tracing back to 5000 BC. They have been a fundamental part of various cultures and cuisines, serving as garnishes, standalone meals, and components in numerous recipes.
