Nutritional Value
Eggs are a powerhouse of nutrition. They provide high-quality protein, healthy fats, and a range of vitamins and minerals such as vitamin D, B12, and selenium. Double yolks offer slightly higher amounts of these nutrients but also more cholesterol.

3. The Science Behind Egg Structure
To understand cooking eggs well, it helps to know what makes up an egg.
Shell: The hard outer layer protects the contents.
Albumen (Egg White): Mostly water and proteins, it provides structure.
Yolk: The yellow, nutrient-dense center rich in fats, proteins, vitamins, and minerals.
When eggs cook, the proteins in both whites and yolks undergo a process called denaturation — they unfold and then coagulate to form solid structures. This is why eggs turn from runny to firm with heat.
The resilience of the yolk membrane keeps the yolk intact during frying, but over time or with high heat, it can rupture.
4. Cooking Eggs Perfectly: Techniques and Tips
Frying Styles
Sunny-side up: The egg is fried on one side, leaving the yolk runny.
Over easy: The egg is flipped briefly to cook the white fully but keep the yolk soft.
Over hard: The egg is flipped and cooked until the yolk is firm.
