How is it done?[edit | edit source]

  • It is a cooking method in which food is submerged in hot fat, traditionally lard but today most commonly oil, as opposed to the shallow oil used in conventional frying done in a frying pan.
  • It can be used to cook foods such as fried chicken, French fries, and potato chips.
  • The process involves submerging a food in extremely hot oil until it reaches a safe minimum internal temperature.
  • When the food is deep-fried properly, it will be hot and crispy on the outside and cooked safely in the center.
  • Deep frying is very fast and, when performed properly, destroys bacteria.
  • Deep frying foods cook quickly as all sides of the food are cooked simultaneously as oil has a high rate of heat conduction.
  • Deep frying is classified as a hot-fat cooking method.

Food safety[edit | edit source]

  • Deep frying oil can reach temperatures of over 400 °F.
  • When cooking at this temperature, extreme safety measures should be taken to prevent burning oneself or starting a fire.
  • Like other oils, cooking oil is a highly flammable liquid.
  • To prevent flare-ups and house fires, avoid letting oil contact direct flames.
  • Because of this hazard, it is highly recommended to have a kitchen fire extinguisher available when deep-frying.
  • Water is a very dangerous liquid when deep frying. When water encounters very hot oil (about 350 °F) water vaporizes instantaneously turning into super heated steam.
  • It expands quickly, which can cause oil to splatter and risk bodily injury.
  • Do not let water get into the hot fat or use water to cool, or clean the appliance while food is deep-frying.
  • In the event of a grease fire, never use water to put out the fire.
  • Using water can cause flaming oil to splatter and spread.
  • A kitchen fire extinguisher or covering the fryer with a metal lid is the best way to put out a grease fire.
  • Call 911 immediately if a grease fire occurs.

Equipment used[edit | edit source]

  • A deep fryer or chip pan is used for this
  • A pressure fryer or vacuum fryer may be used.
  • Deep frying may also be performed using oil that is heated in a pot.
