An egg contains 7 grams of protein and 82 kilocalories of energy, with a nutritional utilization rate of over 98%. It is rich in calcium, phosphorus, iron, and vitamin A, and also contains a good amount of B vitamins, earning it the title of "complete protein model" from nutritionists. You could say that eating an egg is equivalent to a complete nutritional meal.
The most common way to eat eggs is boiled, but boiled eggs are never perfectly intact and beautiful. If you have this problem too, listen to this little trick.
Before boiling the egg, poke a small hole in the larger end with a needle, then place it in the water to cook. This ensures that the heat inside the egg can escape smoothly, and the cooked egg will be both beautiful and intact. If the egg already has a crack, just add some salt to the water, and the white and yolk will not leak out.
