In reply to readysalted:
No idea about the dehydrator but it is something i have thought of myself as i backpack a lot in summer with work but at the moment they are not cheap.
If on a 2 day trip i will carry:
Breakfast: Porridge, milk powder
LUnch: Hummus (can be messy) or sandwich spread (veggie ones are great) and warburtons wraps
Plus snacks of fruit bars,frusli, mars bar
Tea: meal made by 'Look what ive found'
The look what ive found meals are lovely, like homecooked food, no rubbish but are heavy, weighing 250g per pack and you need 2 packs or 1 packs plus pasta.
On more than 3 days i don't think the weight of these meals is worth it and i carry dehydrated meals often by BeWell - not cheap but worth it as some meals are very tasty.
After you have factored in the cost of a dehydrator and the food to put in it and the bags etc, you would probably save some money but not a huge amount unless you use it over a long period and backpack regular.
I know you dont like spending a fiver- neither do i- on a meal but otherwise backpacking is free so i have accepted it as a small cost.
With water it depends on where i am, generally i will drink straight out of streams and rivers and carry 1 litre at a time unless i think it may be hard to find. In scotland most places are fine to drink straight out and i still do in the lakes if there has been good rainfall.
Otherwise i use chlorine to sterilise water or boil everything.
You dont need to filter water your cooking with as boiling it with steralise it, unless it is filled with sediment.
p.s well done on the bacon, you are probably the first person who i have heard of carrying bacon backpacking other than a few kids i take out. It must be worth it but heavy and messy!
