folding twig stove a novelty item only, no end of practical issues
I would very much like not to carry gas or liquid fuel, so perhaps I could overcome these issues -
Fire bans and concerned locals telling you not to have a fire: screen the stove behind bike/panniers/clothes (also works as a wind screen)
Actual risk of setting fire to the undergrowth: clear a bare patch to put the stove on. Be nice to have an implement for this. Preferably something which I'm already carrying. Can't think of anything.
Starting the fire in damp conditions: pack some dry tinder, e.g. a tampon. Then add lots of wood shavings, made on the spot. (I would pack my best knife. Any excuse to use it.)
Lots of black smoke which attracts concerned locals: cook supper after dusk. Cook breakfast after most of your packing is done, so if a local approaches you'll be about to leave
Masses of soot on the pan and the outside of the stove: don't clean them. Pack them v.v.carefully in cloth bags to stop the soot migrating in your panniers.
Lots of wood needed: the food I cook doesn't take long (fry the bacon 'n eggs, or boil water for pasta)
Poor control of cooking temperature: I can live with this for the v. basic cooking that I do. I don't mind holding the pan above the stove.
Excellent tips!
So my One Pan to Rule Them All would be a 1 litre Duossal. 150 grams. 5.9 cm diameter. Just enough for bacon and eggs. https://trangia.se/en/shop/saucepan-1-l-outer/ With the separate Trangia handle, which I've always liked. 48g. https://trangia.se/en/shop/handle-th25/
