I am using an Emberlit Mini wood stove that I am pretty happy with, in combo with an Evernew 800ml kettle and a small plastic cup.
Stove and kettle weight are pretty close to 8oz total. No fuel weight, so with cup and spoon (folding MSR) the total cook set is about 10oz. The storage sleeve is a piece of Tyvek reinforced with a bit of packing tape, and a little Cuben sack for the kettle.
Yes, the kettle is a little sooty, but less than I would have imagined, and surprisingly even less after extended use leaves it with a shiny black glaze. The stove can be disassembled quickly handling just the edges, so not a whole lot of soot ends up on the fingers. With a little practice, of course.
For a fire starter, I am using the cotton balls dipped in melted Vaseline and then wrapped in waxed paper like a piece of hard candy. Very clean handling and very long burn which will ignite very damp twigs.
