I am amazed how many of these “One cooking device to DO IT ALL” there are. In rough time order from when I was aware, I am sure STW can fill in loads more. We get by with and oven and a hob*.
Microwave – we actually have one of these
Pressure Cooker
Slow Cooker
Electric wok
Air Fryer
Theromomix
*Actually 2 double ovens and a 6 ring hob with a special wok ring because I told my wife to get everything she would need designed into the kitchen extension. I thought I meant a sink, plug sockets doors and windows.
