Glad to know you're in better spirits now!
I haven't used Esbit before but I want to try it, so please forgive me if my questions are sort of dumb. I watched the video on your site, and see that the two 4-gram tabs occupy most of the space in the burner. If you wanted to boil a larger quantity of water (I usually boil .75 to 1 liter), I assume you would need about twice as much Esbit. Do you think your stove would still work with that?
