Thanks so much for that insight ... I knew it worked, but I never thought of the fact the MH bags are meant to hold heat. Maybe I'll even try boiling water in one on my bushbuddy, when it gets here -- that would supplement my edible gear and make my carrying weight SUL :)
We dehydrate some of our own foods and they rehydrate pretty quickly, still experimenting after all these years ... posted a review of the Nesco Dehydrator (only like $60 I use, and have for about 12 years or so) under the Cooking threads ...
... while Mountain House stuff costs a bit, we buy the bigger bags with like 4 or more servings and break them down. One normal main course serving for one person + corn + dried mashed potatos or a baggy of really lite turkey stuffing mix, and a bit of other junk like home dried hamburger is enough for two of us = about $ 6.50 for an entire dinner out on the trail. Breakfast is really cheap, muessili w/ dried fruit and nuts we add or flavored instant oatmeal package and a cup of that instant Cappucinno stuff or tea, or lemon juice heated or an EmergenC fizzy in hot weather = about $1.50 for 2, i'm guessing. Breakfast of lunch can be supplemented with Nature's Harvest granola bars for a cereal if we want: powdered milk + water + put the bar in the pot and let it disintegrate into a cold ceral + dried fruits/ nuts/ raisins/ cranberries, etc.
Lunch is whatever, usually more granola bars, dried fruit, homemade jerky (of all kinds) ..... also carry light weight rice crackers, corn puff crackers, and candy that is light weight, sometimes honey for fun, in the little stick packages, and some really syn food meat sticks like the Xtreme Stick or Smokey Joes ... and now am adding Pringles per forum leaders, gurus, gate guarders, and over masters recommendations .... = about $3 - 4 for both of us for lunch/snacks ... paving the trail for us to get to din din ... (really looking forward to bushbuddy & alternative wood stoves to eliminate cost of carrying gas cannisters or fuel, which will help with overall cost issues once bushbuddy pays for itself in few years) ...
.... so the cost of a hot, tasty dinner isn't too bad considering we can get away with one dinner main course package and one vegetable package plus some other stuff we add. Will splurge and get cheap cheesecake mix and divide it up into portions, with the jam top, and make cheese cake -- sometimes works -- sometimes produce whitish paste, like elmers glue with sugar ....(Still trying to perfect instant pudding desert -- generally get instant pudding thick guck desert ... any ideas?)
