What happens to food when you fry it?

When food is fried, it undergoes a process known as frying, where it is cooked in hot oil or fat. The high temperature causes moisture in the food to evaporate, creating a crispy outer layer while the inside cooks thoroughly. This process also leads to the Maillard reaction, which enhances flavor and color. Additionally, frying can alter the nutritional profile of food, often increasing its fat content.
