Egg yolk
Egg yolk is the yellow, nutrient-rich center of an egg. It contains fats, proteins, vitamins, and minerals essential for developing a chick if fertilized. The yolk provides energy and nutrients and has healthy fats, including omega-3 fatty acids. It is surrounded by egg white (albumen), which offers additional protein and moisture. In cooking, egg yolk acts as a natural emulsifier, helping combine fats and liquids smoothly, and adds richness and flavor to dishes like sauces, custards, and baked goods. Its composition varies depending on the diet and health of the hen.
