The air fryer is an essential tool for the modern kitchen. Here are a few benefits of this appliance.The air fryer is easy to use: Simply put food in the basket (or on a rack-more about this later), select the time and temperature, and turn it on. Other than shaking the basket or turning the food over for even cooking or crispness, the machine does all the work. Some air fryers come with preset functions and buttons for different foods, such as French fries, frozen vegetables, bacon, fish, and chicken, which eliminates any guesswork, even if you aren't following a recipe.This appliance is energy efficient, and it won't heat up your kitchen like an oven or stovetop. An air fryer keeps heat inside the unit by using a heating coil to warm the air, then blows that hot air around with a high-speed fan.
