Air fryers are some of the most versatile kitchen appliances around, letting you coko everything from a whole chicken, heaps of veggies, desserts, burgers, pizza, and more. However it’s important to know which foods are off-limits, as making the wrong choice can ruin your dinner, and possibly your air fryer in the process. First, stay away from battered foods. Anything dripping wet will end up sticking together and clogging the fan of your air fryer. Leafy greens are a similar problem, as the strong hot air currents will blow them around inside the basket. Cheese is another one to stay away from, as the heat currents will simply melt it.
