Scientists Reveal the Secret to the Perfect Boiled Egg—And It Takes 32 Minutes!

Boiling an egg may seem like a simple task, but Italian scientists have developed a new technique that takes precision to a whole new level. According to researchers from the Italian National Research Council, the perfect boiled egg requires exactly 32 minutes of cooking using a method called periodic cooking. This technique involves alternating the egg between boiling water at 100°C and lukewarm water at 30°C every two minutes for the entire cooking process.

The Science Behind Periodic Cooking

Traditional methods of boiling eggs usually involve submerging them in hot water for a set time. However, this often leads to inconsistent textures—some eggs end up with overcooked yolks and rubbery whites, while others remain too soft. The new periodic cooking method aims to achieve the ideal balance between firmness and creaminess by precisely controlling the temperature.

By moving the egg between two different water temperatures, scientists believe they can regulate heat diffusion more evenly. This prevents the egg white from becoming too tough while allowing the yolk to reach its perfect consistency without overcooking. The result? An egg with a tender, silky white and a perfectly structured yolk.

Why Does It Take 32 Minutes?

At first glance, a 32-minute cooking time may seem excessive, considering that most people can boil an egg in under 10 minutes. However, scientists explain that the alternating temperature technique slows down the cooking process in a way that enhances the egg’s final texture. The controlled heat exposure ensures that:

✔ The egg white remains firm yet delicate rather than rubbery.

✔ The yolk achieves a smooth, custard-like consistency rather than becoming dry or chalky.

✔ The overall taste and texture are more refined compared to traditional boiling methods.

How Does This Compare to Traditional Egg Cooking Methods?

Most people use one of the following methods to boil eggs:

Soft-boiled (6–7 minutes) – Whites are set, but the yolk is runny.

Medium-boiled (8–10 minutes) – Whites are firm, and the yolk is slightly creamy.

Hard-boiled (12–14 minutes) – Whites and yolk are fully solid, often with a chalky texture.

The periodic cooking method challenges these standard times by introducing alternating temperature phases, which distribute heat more evenly. The result is a boiled egg that avoids the common pitfalls of overcooking or undercooking.

Is It Practical for Everyday Cooking?

While the periodic cooking technique may be scientifically fascinating, its practicality for home cooking is questionable. Most people prefer a quick and easy approach to boiling eggs, and a 32-minute process with temperature changes every two minutes requires more effort than simply setting a timer.

However, for chefs, food enthusiasts, and gourmet restaurants aiming for precision cooking, this technique could be a game-changer. It provides a scientific approach to achieving a perfectly boiled egg, which might appeal to fine dining and molecular gastronomy experts.

Could This Change How We Cook Eggs?

While it’s unlikely that everyone will start using the periodic cooking method for their daily breakfast, it does highlight the importance of temperature control in cooking. Many cooking techniques rely on gradual heat application to enhance food texture, and this study adds to the growing knowledge of how precise temperature changes can improve even the simplest foods.
