Deep frying (also referred to as deep fat frying ) is a cooking method in which food is submerged in hot fat, most commonly oil, rather than the shallow oil used in conventional frying, done in a frying pan. Normally, a deep fryer or chip pan is used for this; industrially, a pressure fryer or vacuum fryer may be used. Deep frying may also be performed using oil that is heated in a pot. Deep frying is classified as hot- fat cooking method. Typically, deep frying foods cook quickly: all sides of a food are cooked simultaneously as oil has a high rate of heat conduction.
The term "deep frying " and many modern deep-fried foods were not invented until the 19th century, but the practice has been around for millennia. Early records and cookbooks suggest that the practice began in a few European and Arabian countries before other countries adopted the practice.
Deep frying is popular worldwide, with deep-fried foods accounting for a large portion of global caloric consumption. Many foods are deep-fried and cultures surrounding deep frying have developed, most notably in the Southern United States, where many events dedicated to deep frying food and non-edible items are held.
