(I did a search and if the answer's buried in there I couldn't find it. <img src="/forums/images/graemlins/tongue.gif" alt="" /> )

Is there any convenient way to snuff it and then drain the leftover fuel back into the bottle once it cools? I currently have a heavy-ish Trangia, which has a snuffer/simmer lid, and a cap to save the leftover fuel for next time. The catfood-container stoves I've played around with don't seem any faster (if not slower, even) than the Trangia, but do save a lot on weight and are easily drained.

I really like the simplicity & claimed performance of the White Box, but it looks like it's meant to burn itself out with every use, which doesn't seem very flexible, and could hurt fuel efficiency until you are spot-on at guessing meal prep times.

Aside - how does the air get in?
