Deep frying is a cooking method that involves submerging food in hot oil, typically at temperatures between 350°F and 375°F (175°C to 190°C). This technique creates a crispy outer layer while cooking the food inside quickly. Common foods that are deep-fried include potatoes for French fries, chicken, and doughnuts. The process begins by heating oil in a deep fryer or a heavy pot. Once the oil reaches the desired temperature, the food is carefully added, allowing it to cook evenly. After a few minutes, the food is removed and drained of excess oil, resulting in a flavorful and crunchy dish.
