what's an air fryer?

     An air fryer is a small countertop convection oven designed to simulate deep frying without submerging the food in oil.[1][2] A fan circulates hot air[1] at high speed, producing a crisp layer via browning reactions such as the Maillard reaction. Some product reviewers claim that regular convection ovens or convection toaster ovens produce better results[3][4][1] or that air frying is essentially  convection baking under a trendy new name.[5]

  Interior of an air fryer

Air fryers use a circulation of hot air to cook food that would  otherwise be submerged in oil. The air fryer's cooking chamber radiates  heat from a heating element near the food, and a fan circulates hot air.[1]  The temperatures can go up to 250 °C (482 °F) depending on the model.  Cooking oil is not used in large quantities in an air fryer. Cooking  times in the air fryer may be reduced by 20% or more, as compared to  non-convection ovens.[citation needed]

Traditional frying  methods induce the Maillard effect at temperatures of between 140 to  165 °C (284 to 329 °F) by completely submerging foods in hot oil,  well above the boiling point of water. The air fryer works by coating  the desired food in a thin layer of oil while circulating air heated up  to 200 °C (392 °F) to apply heat and initiate the reaction.[6] As a result, the appliance is able to brown foods like potato chips, chicken, fish, steak, cheeseburgers, french fries or pastries using 70% to 80% less oil than a traditional deep fryer.

Most air fryers have temperature and timer adjustments that allow  more precise cooking. Food is typically cooked in a basket that sits on  a drip tray. The basket must be periodically agitated, either manually,  or by an integrated food agitator.[2]  Convection ovens and air fryers are similar in the way they cook food,  but air fryers are generally smaller and give off less heat.[2] 

The taste and consistency of foods cooked using traditional fried methods compared with air fried techniques are not identical,[1]  because the larger quantity of oil used in traditional frying  penetrates the foods (or the coating batter, if it is used) and adds its  own flavor.

Some air fryers are equipped with additional accessories for  specific kinds of cooking, such as pizza pans, skewer racks, grilling  trays, and cake barrels.

Like standard convection ovens, air fryers can also roast, steam, and dry food.

Convection ovens have been in wide use since 1945.[7]

In 2010, Philips  introduced the Airfryer brand of convection oven at a consumer  electronics fair in Berlin. It used the patented Rapid Air technology.[8] The term "airfryer" is now often used generically.[9]

Early air fryers were barrel-shaped. More recently, many have come to resemble toaster ovens and pressure cookers, and share their functions.

According to Consumer Reports in 2019, the five top brands of air fryers in the USA were Elite, Farberware, GoWISE, Ninja, and NuWave.
