According to a recent YouTube video, air fryers and convection ovens work in effectively the same way, with a coil stove element and fan, the main difference being a fryer’s small size.
This means they can heat up more quickly and apply heat more precisely for smaller batch cooking, but the advantages may not outweigh the extra cost and space for a separate appliance, suggests the video.
Air fryers may also be more powerful, with hotter air and fans that can cook and burn food faster.
Cooking with a denser gas or higher pressure could also improve results.
Conversely, a hack using a microwave and heat gun can make cookies faster, while innovative food design can improve cooking, such as ramen in an edible package or origami noodles.
