1, stitch: After the eggs are washed, use the sewing needle at home to make a small hole in the bottom of the eggs, not too deep or too hard, just gently make a small hole. Because there is an air chamber at the bottom of the egg, when the egg is cooked, the air in the eggshell will slowly leak out through the small hole and the eggshell will not break.

2. Soak in cold water: After washing the eggs, soak them in a basin filled with cold water for half an hour to reduce the air pressure inside the eggs, then cook them on the fire, boil them in water for another 5 minutes, and then soak them for another 5 minutes after turning off the fire, so that the eggshells will not be broken.

3. Cook on medium fire for no more than 65,438+00 minutes: when the fire is fired, the air pressure of the egg rises rapidly, the egg expands, and the eggshell is easy to crack; The heat is too small, which is easy to cause the eggs to be boiled white and not cooked yellow; Therefore, boiled eggs should be cooked in medium heat, and the cooking time should not exceed ten minutes. If the time is too long, the nutrients of the eggs will be reduced after cooking, and the eggs will become hard and unpalatable, which will affect digestion and absorption. Uncooked eggs are undercooked. Control the heat and time, and the eggs will not break easily.

4, salt, vinegar method: when cooking eggs, you can add a little salt or vinegar to the water, a little can soften the eggshell, eggshell is not easy to crack, easy to peel after cooking.
