What is Deep frying?
[[File:Frituren.jpg|thumb|Deep frying]] [[File:Namche Bazaar, Deep frying, Deep fryer, Nepal.jpg|thumb|Deep frying]] '''Deep frying''' is a way of [[cooking]] food by putting it in hot [[Cooking oil|oil]] or [[fat]]. Deep frying cooks food very quickly. Deep frying is popular in the [[United Kingdom]] - one dish popular in the United Kingdom is [[fish and chips]]. == Technique == [[File:Fried calamari.jpg|thumb|left|Breaded, deep-fried [[calamari]]]] [[File:Fried pork intestines.jpg|thumb|Deep fried [[pork]] [[Large intestine|intestines]]]] If done well, deep-frying does not make food too greasy, because the [[moisture]] in the food repels the oil. The hot oil heats the [[water]] in the food, [[steaming]] it from the inside out. The water vapor pushes the bubbles toward the surface of the oil.<ref>{{Cite book | first = Hervé | last = This | author-link = Hervé This |others= trans.

However, if the food is cooked in the oil for too long, much of the water will be lost and the oil will begin to penetrate the food. The correct frying [[temperature]] depends on the thickness and type of food, but is usually between 175 and 190 °C (345–375 °F). Some fried foods are given a coating of [[batter (cooking)|batter]] or [[breading]] prior to frying. This makes the outside of the food crispy and browned, while the inside becomes tender, moist, and steamed. Some foods – such as [[potatoes]] or whole, skin-on [[poultry]] – have a natural coating and do not require breading or battering. == Disadvantages == Deep frying makes large amounts of [[Cooking oil#Waste cooking oil|waste oil]]. Getting rid of the oil properly may be a problem. Waste oil is increasingly being recycled into [[biodiesel]]. Some deep fry [[shortening]]s have [[tran
