ETSU,
These days I use Esbit whenever I'm solo, which is most of the time. It's not at all fussy. I used rocks and foil a lot and it's easy to do (two or three small rocks as windbreak/pot support and a little square of foil on the ground - to protect ground and reflect heat).
I have since bought one of the tiny titanium wing stoves and made an aluminum windscreen. The windscreen fits neatly in my pot. It has the bottom cut up about a quarter of an inch leaving three "legs" (more stable than four) on the ground and a ring of ticket-punch holes near the top. It also has a couple tabs on the end I can crimp together to hold it together.
It just curls around the pot wall on the inside for storage, overlapping about an inch and height is just short of the lid. It started life as an aluminum foil single-use roaster pan.
Cut it down with ordinary scissors, probably in less time than it took to write this. Works like a charm. I still use a piece of foil on the ground (cut in circle to fit in the bottom of my pot.
Best, jcp
Yeah! I was thinking about those too, using rocks for pot support, aluminum foil as a windscreen, etc.
This is the pot support I'm looking at:
