Homemade sublimates on a hike in Nepal

For the last couple of years, I have been actively using homemade sublimates while hiking in Nepal. This is a completely optional thing - in Nepal you can eat great local food. However, if you want to save some money on trekking, or are going to remote areas of the Himalayas where there are no shelters, then you might be interested in watching me cook lunch at an altitude of 4700 meters (Everest Base Camp Trek).
