1. Why is cooking a soft-boiled egg an art?

Have you ever dreamed of an egg with a soft, set white and a runny, velvety yolk that gently stretches when you cut it? That's it, that's the soft-boiled egg, that simple little joy that can quickly turn into a disaster if you mess up the cooking. However, cooking a soft-boiled egg isn't a mystery or a whim of a star chef, just a knack to acquire—and we're going to pass it on to you, grandpa.

In this comprehensive guide, we break down step-by-step the technique, timing, and a few clever tips for making every soft-boiled egg like a pro—even if it's your first time.

2. The easy technique for making a perfect soft-boiled egg

Before you begin, here's an important tip: take the eggs out of the fridge and let them sit at room temperature for 15 to 20 minutes. This prevents thermal shock and reduces the risk of cracking. It's not mandatory, but it helps a lot.

1. Prepare a saucepan with enough water to completely submerge your eggs (not too much, not too little). Add a pinch of salt to reduce the risk of the shell cracking.
2. Bring the water to a gentle boil : not a big boil otherwise it will hit the eggs and… break.
3. Gently lower them in with a spoon, one by one.
4. As soon as the eggs are in the water , start your timer for about 6 minutes 30 seconds (varies depending on the size of the egg).
5. Prepare a bowl of iced water into which you will plunge the freshly cooked eggs to stop the cooking process.
6. After the iced dip , gently tap the shell and peel your egg gently.

3. Time and tips for perfect soft-boiled eggs

Some tips to avoid the hassle:

• Always immerse eggs in simmering water, not boiling water.
• Use an accurate timer, a few seconds' error can ruin the texture.
• Finally, the thermal shock in the iced water is your ally to stop the cooking at the right moment.
• Don't leave your eggs in hot water after cooking, they will continue to cook (and end up hard-boiled).

4. Variations and recipe ideas with soft-boiled eggs
