Hi, Rusty!
I have been doing a bit of research ... it seems that one can buy electric soup kettles that you can plug in and use on a kitchen work top, as well as the type that go on top of the stove.
These can be available in varying small sizes; an average being around one litre capacity, aimed at soup for two to four people.
Interestingly, one can also buy them with a "smoothie" setting, so that healthy fruit drinks can be made , too!
I know you like making "smoothies"!
At present we make our soup in a large saucepan on top of the cooker.
That works well, but might be nice to compare options?
I might take a look when I next go to Currys....
