What Is an Air Fryer and How Does It Work?

The air fryer is a popular kitchen appliance. It works by swirling hot air around the food. The hot air reaches all the surfaces of the food, making it crisp. Even though the food cooked in air fryers looks and tastes like deep-fried foods, no oil gets used. 

How Do Air Fryers Work?

The fact is air fryers don’t fry any food. After you place the food in the perforated basket, the appliance cooks the food by blowing hot air around it. The air gets swirled quickly in a circular fashion.

A convection effect gets produced due to the force of the air. It helps cook and brown the exteriors of the food. When the air temperature reaches more than 160C, foods such as frozen chicken, tater tots, and french fries will turn brown.

As the food sits in the basket, it increases contact with the hot moving air. The lack of space between the basket and the walls of the chamber intensifies the heat. It ensures quick, crispy cooking.

One big convenience that air fryers provide is that you will be able to reheat food quickly. When you reheat crispy foods, they will continue to remain crisp. Most often, food heated in a microwave oven tends to turn soggy.

How Do You Use Air Fryers?

Here is how you can use an air fryer.

Step 1:

Place the food in the basket. Depending on the basket size, you can choose the amount of food to place in it. If you want to increase further the crispiness of food, you can choose to add a teaspoon of oil to the food.

Step 2:

Set cooking time and temperature. The cooking time ranges from 5 – 25 minutes. The temperature often ranges from 325° to 400°F. The cooking time and temperature setting will depend on the type of food you are cooking.

  • Ease of Use – The controls should be simple to understand and use. You should be able to detach the basket with ease for cleaning.
  • Capacity – The amount and type of food that can get cooked in an air fryer is another critical factor to consider. Most fryers can cook 1.8 – 2.5 pounds of food. If you want to cook more food, you should opt for a bigger size of fryer.
