A kitchen should, first and foremost, be convenient. That means storage is neat, counters are clear, and appliances are easy to use. In a small kitchen, however, it is easy to be overwhelmed and struggle to achieve any of the three.
In my tiny cook space, my air fryer was always getting in the way. A bulky, dual-drawer model, it is too big for my limited counter space, and too awkward to put anywhere but at the front of a cabinet. As I don't use it every day, it gets in the way of my everyday kitchen storage. It's a constant inconvenience.
