Small, very concentrated convection ovens. I have both a medium sized convection oven and an air fryer. They do different things well.
I can bake stuff in my convection oven but would never try to get a crisp fried chicken from it.
I should try this. We recently moved, and now have a gas stove, the over heats up INSANELY fast and I swear food cooks faster in it even with the fan off (Is there some humidity factor?).
This was so uncanny I did some direct comparisons with the oven in our old house (Went back to clean it up for a weekend). And it actually cooks things faster, after preheat. Literally no idea why.
It’s probably just a higher end appliance. After growing up with my family only ever getting used ovens and replacing with more used ovens when they broke, I finally tried a more expensive new unit and it was an induction stovetop with convection oven and it’s unreal how different it is. I still use the air fryer pot lid for various things though.
Gas (UK) delivers heat much faster than electric does. This is part of our problem in changing over from “conventional” fuels to electric, and the reason why I remember my mother’s gas eye level grill so fondly. Cheese on toast under a gas grill was so much better than you can ever do under an electric one. Recent fan ovens help, but you’re still limited to the amount of KW compared with the insane calorific value of fossil fuels per unit of volume.
