To deal with that issue, this device comes equipped with a fan and an exhaust system that work in tandem to circulate the hot air and to vent it out. The circulation of hot air will eventually lead to an even temperature.

The science behind one of these best appliances it is that the circulating air will speed up the way heat is transferred. Rather than the air just staying in one area and surrounding the food, the fan allows it to be blown directly onto the food.

So, for instance, if the recipe advises you to bake an item for one hour, you should bake it for no more than forty-five minutes.

The time and temperature adjustments are recommended as they tend to be hotter than traditional versions. Additionally, to get the full benefits, your baking pans should have low sides so that the air can circulate adequately and evenly.
