Good thread idea, Snowman, I'm surprised this question hasn't been raised before
Personally, I have yet to try dehydrated food. It sounds a thoroughly miserable experience, and I hate red wine anyway, let alone the dehydrated stuff - my God, why would ANYONE want to put themselves through it!
I used to take dry noodles with me, but they do nothing for energy, now I only take cold foods, pre-prepared pasta trays with some assorted veg, buy a Mars bar in every village and always, always, have a five pack of pepparammi with me
Drinks wise, on a day's excursion, a flask is a must! There's nothing like sitting on a hill, on a windy day, toasting the racing clouds with a fine, strong coffee! Anything longer, then I'm afraid I downgrade to water, or Lemon barley. Though if a village happens to be around, and there is an enterprising shopkeeper there, then a Lucozade Sport is always good!
Would be interested to hear some other people's comments on dehydrated foods, you'll have to try hard to convince me though I'm afraid ..
Personally, WW, I think canned foods and walking (or cycling) just don't go together. I doubt the energy you'd get from eating the contents would replace that spent carrying 'em.
