During my time with the Mountain/Desert Rescue Team at Sharjah the trick with compo (for that is what we were issued with on exercises) was to dump virtually the entire contents of a 10 man pack into a large pot and add a full tin of curry powder.
.....and by everything I do mean everything - except the toilet paper and matches! (in fact I think that the toilet paper went in on one occasion - just to prove it could be done). The matches were never put in - we needed them to light the farts afterwards.
