Understanding Air Fryer Cooking
What is an air fryer?
An air fryer is a kitchen appliance that is designed to mimic the crispy texture and taste of deep-fried food without the need for excessive amounts of oil. It uses a convection mechanism to circulate hot air around the food, which results in a crispy exterior and a moist and tender interior. Air fryers have gained popularity in recent years as a healthier alternative to deep frying, offering a guilt-free way to enjoy fried foods.
How does an air fryer work?
The working principle of an air fryer revolves around the circulation of hot air at high speeds. The air fryer has a heating element that produces the heat, and a powerful fan that circulates the hot air rapidly inside the cooking chamber. This rapid circulation of hot air creates a convection effect, which cooks the food by transferring heat energy through the air, ensuring even cooking and a crispy texture. The food is placed in a basket or on a tray inside the cooking chamber, allowing the hot air to penetrate and cook it from all angles.
