Overcooking also intensifies the sulfur smell often associated with boiled eggs, which can detract from their overall appeal.Fortunately, preventing this issue doesn’t require advanced techniques—just a few simple adjustments to your method will ensure perfectly cooked eggs every time.The Surefire Way to Make Flawless Hard-Boiled Eggs1. Start ColdBegin by placing your eggs in a single layer at the bottom of a pot, ensuring they aren’t overcrowded. Cover them with cold water, leaving about 3–5 cm (1–2 inches) of water above the eggs. Starting with cold water helps heat distribute evenly, reducing the risk of cracking during cooking.2. Heat GraduallyBring the pot to a gentle boil over medium heat. Avoid cranking the heat up too high, as rapid boiling can cause the eggs to bump against each other and crack. Once the water reaches a boil, turn off the heat and cover the pot.3.
