Frying is a cooking method that involves heating oil or fat in a pan to cook food quickly. When food is submerged in hot oil, it becomes crispy on the outside while remaining tender on the inside. Common foods that are fried include potatoes, chicken, and doughnuts. There are two main types of frying: deep frying and pan frying. In deep frying, food is fully submerged in hot oil, while in pan frying, only a small amount of oil is used, and the food is cooked on one or both sides. Frying is popular for its ability to enhance flavors and create appealing textures.
