This is just....not logical....hot air does not 'fry' food, it bakes it, right?
Correct. My research (limited to today) is saying it's basically a countertop convection oven. That would explain all the oil peeps use to coat the "air fried" food of choice.
My reading up on them is showing results that basically anything you would cook in the big oven can be done in the "air fryer".
