While making fried eggs with my friend, I was surprised to see her add a splash of vinegar to the eggs in the pan. Why would you do that?

Understanding the Role of Vinegar in Cooking
Vinegar, a versatile kitchen staple, is celebrated for its ability to enhance flavors and transform dishes. In various culinary contexts, vinegar is known for tenderizing, balancing flavors, and even preserving. The inclusion of vinegar in unexpected recipes often serves a greater purpose than just adding tanginess.
The Science Behind Vinegar and Eggs
Acidic in nature, vinegar interacts with proteins in eggs. When heat is applied, vinegar can chemically denature proteins in egg whites, leading to a firmer and more cohesive texture. This interaction is particularly useful in certain cooking methods to achieve desirable consistency.
