I’m not a fan of single-purpose appliances (microwave notwithstanding), and I recently got a toaster oven / air fryer / grill (so no microwave) and I love it. Haven’t used my full size oven in the 3 months I’ve had this one.
The “Trivection Oven” (as seen on 30 Rock) is a real appliance, and includes microwave heating as one of the 'vections. I believe the microwave heating is just to speed up cooking with the thermal and convection heat for crisping.
Are they a gimmick? Honestly, no clue. I’ve not used one, but the logic checks out and Alton Brown approves.
Yeah. I read a bit more since I commented, and Alton Brown doesn’t just approve - he actually helped design it.
The cost of those is definitely why I still have a mono-vection oven haha.
