A while ago I posted something about cooking without a cooker but if you're really wanting to push things, could you go further? Maybe there's a way you could dispense with the pot / mug altogether and replace it with something much lighter, infinitely cheaper and available pretty much everywhere ... the humble plastic bottle, that's right I did say plastic.
I've chosen the thinnest, poorest quality one I could find. It's not special, it once contained spring water from somewhere or other like countless bottles on the shelves or in the bin ... something a little more substantial will obviously last longer, maybe even a couple of days use. Have a rummage through the bins and see what you can find.
The first thing you'll need to do is light yourself a little fire. It doesn't have to be worthy of Guy Fawkes, just enough room for your bottle to be placed in the middle.
|You'll be needing one of these.|
When you've got a reasonable amount of hot embers, scrape a hollow in them and place your bottle in it. Remember to remove the lid first and only fill it 3/4 full to allow a little expansion (water) and contraction (bottle) room.
|Oi - take the lid off first.|
Add a bit more fuel to your fire concentrating around the outside of the bottle. Don't go mad, you do need some flames but you're not trying to re-make the Towering Inferno.
|Pop the bottle on and put a put a bit more wood ont' fire.|
Sit back and relax. You'll obviously need to keep feeding your fire but within a few minutes you'll have lovely boiling water.
|Hard to see but the water is boiling here.|
If you're going for the full dirt-bag approach just empty your favoured powered beverage straight into the bottle and give it a little shake.
|Not pretty but enough life left for the mornings brew.|
Although not exactly unscathed by the ordeal, your bottle will still hold water and should be capable of a couple more 'burns'.
